Product: Debt collection

On XX/XX/XXXX was given XXXX  services for the amount of {$1600.00} On XX/XX/XXXX attempt were made to get payment from insurance but bill was sent to the wrong department. Company was contacted and informed of the correct insurance department and provided with both primary and secondary insurance, my husband originally mad the call to get information and was told to supply my step father insurance, which i did as mentioned above. On the statement it showed that this was done twice for the the same date ( XX/XX/XXXX ) On XX/XX/XXXX was given emergency XXXX for the amount of {$240.00} making the total balance {$1800.00} this statement was sent XX/XX/XXXX I reached out to both insurance and the company and was told to disregard any bill that came for that amount and that they will be resubmitting the claim On XX/XX/XXXX the original company sent a letter was sent requesting payment in the sum of {$1800.00}. My husband and I reached out to the original company and my primary insurance who paid {$460.00} On XX/XX/XXXX at XXXX I made a call to the original company that had my bill and was told that the bill was being sent over to my primary insurance ( stepfather 's insurance ) and it was going to be a new bill. 
Not long after proving this information i was informed that my bill was sent over to collections, I called and spoke to the collection agency and told them about both my insurance. 
The bills stopped coming so I thought okay everything is resolved, on XX/XX/XXXX ( XX/XX/XXXX ) I  got a letter from the collection agency looking to collect {$1300.00} On XX/XX/XXXX ( XX/XX/XXXX )  another latter was sent by the collection agency for the amount of {$1100.00} but I should pay the full balance of {$1800.00} Pior to all this I had already reached out to both insurance companies. My primary insurance paid {$460.00} and was told to call secondary insurance the following week and to disregard statements from the original company and also if nothing happened t call original company ( the number they provided was not working. On XX/XX/XXXX I called my insurance to follow up the claim was resubmitted and an EOB was sent to my secondary insurance, while my insurance were working on this claim the original company sent my bill to collection knowing that a claim was submitted. 
To add insult to injury the company billed both my insurance for {$1900.00} which is different from the original bill that was sent to me for {$1800.00} luckily my secondary insurance paid {$44.00} because everything was in network {$1400.00} was paid leaving me with a {$0.00} balance, this claim was processed XX/XX/XXXX but also there were two other claims log for this said procedure that was processed on XX/XX/XXXX and for XX/XX/XXXX. 
moving on! On XX/XX/XXXX at XXXX collectors contacted me once again, there was nothing in the mail ( 30 day notice ) leading up to this call. They tasked if I wanted to pay the full amount which I said no to, then they asked me if I wanted to set up a payment plan, i also said no to this and that I will have to speak to my insurance before i do anything. I reached out to both my insurance, first with my primary who did a three way call with the collection agency but we were later hang up on ... so we called the original company who said they have nothing on file and was n't able to give any information because my bill was sent to collection ... So we called my secondary insurance which varied all that was mentioned above and agreed to call the collection agency with both myself and my primary insurance on the call. My secondary insurance provided the information needed and then we were all told that my account will be put on a temporary hold until further notice and then they hang up on us. I was on the phone for 1 hour and 20 mins trying to get this resolved and i have a XXXX XXXX old! 
Based on the information provided i owe nothing to this collection agency but they have been sending me letter/bills and calling me for payment for a procedure that was done because i was having a XXXX, i XXXX a child and the constant calling and letters is not helping, i just want this behind me it has been almost two years!!!!!!!!
