Complaint sub-issue: Attempted to collect wrong amount

On XX/XX/2018, I was looking online for a freight company, to deliver a copy/scanner machine ( XXXX XXXX XXXX ) from XXXX XXXX XXXX to XXXX XXXX   XXXX. I was comparing rates and quotes with different companies. I managed to find XXXX XXXX ( The Broker ) thats located in XXXX XXXX XXXX. The Broker gave me a price quote in the amount of {$440.00}. I booked with ( The Broker ) and paid by XXXX {$440.00} ( copy of the payment attached ) ( Page 2 and 3 of XXX ). The Broker was charging {$1.00} per pound, and {$6.00} per cubic foot. My total weight was 280 lbs. ( Thats including the pallet thats the shipment was on, copy of the customer estimate and agreement attached, page 5 of XXX ). The Broker gave me a freight company by the name of XXXX XXXX XXXX XXXX. The name of the company is clearly shown on the bill of landing ( top left hand corner on page 6 of XXX ). According to XXXX official website the weight of XXXX copier/scanner is 192.9 lbs. if you add the pallet thats the shipment was on, thats about 80 lbs. Thats 273 lbs. total. We paid for 280 lbs. On bill of landing and customer estimate agreement you can clearly see the price and the weight we paid for ( Pages 5 and 6 of XXX ). 
On XX/XX/2018 a truck pulled up to our place of business at XXXX XXXX   XXXX XXXX. Driver, had all of my information, where to pick up the package, what the package is, how much it weights, whos the shipper and whos the receiver. 
On XX/XX/2018, I got a notification from The Broker to log in into my online account. When I logged in, I was presented with a bill in the amount of {$790.00} ( copy of Billing Adjustment attached, page 7 of XXX ). On the billing adjustment it states, that I owe additional monies for my shipment. Apparently a licensed freight inspector documented the discrepancies. There was a discrepancy either in my weight, size or the item that was shipped. It also states that a copy of the report attached. There was nothing attached. I called The Broker and asked them to provide me with the report. They still have not provided me with one to this day. When I called The Broker and asked them for a copy of the report from the licensed freight inspector, I was told there is no report and they are charging me for Miscellaneous Fees. They want an additional {$1000.00} in Miscellaneous Fees are they serious??? What kind of fees is this??? I understand if there was Miscellaneos Fees of an additional {$100.00} or {$200.00}, I understand, but {$1000.00} thats ridiculous. Since Ive paid The Broker already {$440.00} and they want an additional {$790.00}, and they charge {$1.00} per pound by my calculations the shipment should weight about 850 lbs. The copy/scanner machine itself weight 192.9 pounds. Why am I being charged for 850 lbs? To my understanding, the way Broker works is they would charge a customer X amount of $ for their services, find the lower rate with some other company, collect $ from the customer, keep some kind of percentage for themselves and the rest goes to the company with who they found the cheaper rate. Furthermore, as of right now, Ive been placed in collections with Hunter Warfield in the amount of {$1000.00}. Why??? Ive paid for the services that were provided to me. Im attaching a copy of the sales receipt when I sold the copy/scanner machine to somebody in XXXX, XXXX. Since I dont have the means of transporting the equipment there myself, Ive hired a company for me to do so. 
All the documents that I was able to gather, it show different amount of monies owed. On page 7 of XXX it shows I owe {$790.00}. On page 8 of XXX it shows I owe {$1100.00}. On page 9 of XXX, it shows I owe {$1000.00}. 
I am also attaching a copy of the XXXX tracking information, stating the package was delivered. Furthermore, shipment weight was corrected on XX/XX/2018 at XXXX XXXX. Total shipment weight was corrected to 395 lbs. 
Honestly, this is not how you do business!! Ive paid for the services that were provided to me. Now our company is being sent to collections. Ive called ( The Broker ) and they cant help me at all. They want me to pay an additional {$1000.00} for something that was paid already. I kindly ask you to look into this matter. If you require any additional information or you have any questions, please do not hesitate to contact me at XXXX. Or XXXX XXXX
