Product: Debt collection

In XXXX XXXX I received a statement from my XXXX XXXX card showing a charge of {$72.00} by XXXX in XXXX XXXX ( this credit card was on file with XXXX ). I disputed the charge because it was not mine and XXXX XXXX credited my account. Later the same month XXXX XXXX sent me 2 letters, one stating they had contacted XXXX and the other stating they 'd yet to hear back from XXXX regarding the situation ; pending no followup from XXXX, I could consider the matter closed as of XXXX XXXX, XXXX. 

However, in XXXX I received a " Past Due '' invoice directly from XXXX for the same charge. I called XXXX on XXXX XXXX, spoke with a woman named XXXX, was able to get details regarding the charge and told her why I was disputing it ( I live in XXXX, the delivery charged to my account was out of XXXX, and the delivery was to XXXX ), and she credited my account and closed it. 

In XXXX XXXX I got a demand letter from XXXX stating my balance was past due! Despite it was supposedly closed in XXXX! On XXXX XXXX I called XXXX, spoke with a woman named XXXX in the Fraud Department, explained the circumstance, and she opened a case ( # XXXX ). I got a phone call from her on XXXX XXXX letting me know she had seen a scan of the delivery receipt in question ( where I was mistakenly billed ), that it was a billing error ( incorrect XXXX account number entered by clerk ), that it was not fraud but a mistake by XXXX, and the case was closed. 

Suddenly in XXXX XXXX I got a nasty " Statement of Recovery Enforcement '' from XXXX XXXX XXXX ( account # XXXX ) on behalf of XXXX, regarding the same charge and balance, despite it had supposedly been taken care of twice already!! I emailed XXXX 's collections department, explaining the situation ( again ), on XXXX XXXX. I then received a letter ( dated XXXX XXXX ) from XXXX XXXX ( not XXXX ) stating they were ceasing collection efforts. 

I was away on a business trip with my husband from XX/XX/XXXX-XX/XX/XXXX, and at XXXX point, when I called our home to check voicemail messages, there were a few voicemails from another collection agency in XX/XX/XXXX ( I do n't remember the name of the agency, nor do I have the number of the agent on my case ). I did call the number twice and left voicemails ( I did not write down the name of the individual because I could n't understand the name ), although in my 2nd voicemail I briefly explained the situation and that they need to contact XXXX because it was taken care of. I never received another call and assumed this was ( again ) resolved. 

Then on Thursday, XXXX XXXX, XXXX, I suddenly received a " Seriously Past Due '' invoice from Transworld Systems Inc XXXX file # XXXX ) regarding the same XXXX charge from XXXX XXXX!! Supposedly this had been taken care of three times, presumably four ( when I did n't received a return call in XX/XX/XXXX ) and now past-due charges have been applied, totaling a balance of {$82.00} ( {$72.00} + {$10.00} )! 

I am at my wit 's end!! I have contacted everybody I should have to get this resolved, and now I have another company harassing me!! I do n't know what else to do but report XXXX, XXXX XXXX XXXX, and Transworld Systems for constantly contacting and harassing me, for a mistake XXXX made, when I 've made multiple attempts to resolve XXXX 's mistake and had supposedly had it taken care of multiple times!
