I ended service XXXX on XX/XX/XXXX. After receiving my final statement I notice some additional charges that needed to be corrected. Contacted on XX/XX/XXXX and informed them of the errors. A ticket was created to amend bill and a new updated bill will be sent in 7 to 10 business days. Bill never received. Called XXXX XX/XX/XXXX in regards to bill. Customer service observed bill was still waiting on supervisor approval for corrections. Another ticket was created and marked urgent for corrections and new bill. On XX/XX/XXXX received a credit alert stating that my XXXX account was turned over to a third party collections agency. Spoke with the representative rom Southwest Credit and they stated that they were XXXX attempting to collect on a past due bill for {$510.00}. Explain to them that the charges were incorrect and the bill was being reviewed for corrections. Requested to be transferred to billing and at that time they stated they were a third party collections hired by XXXX. I contacted XXXX XX/XX/XXXX and spoke with XXXX ( # XXXX ) who reviewed my bill with her supervisor and corrected it, She also sent a request to remove my account from the third party collections ( # XXXX ). On XX/XX/XXXX contacted XXXX to check on the status of my account and it was still in collections. The customer service representative stated that the first request was denied and the collection agency refused to remove at the request of XXXX. She then created a second ticket ( # XXXX ) which requested that the account be removed from collections. On XX/XX/XXXX the collection agency updated the payment amount from {$510.00} to {$360.00}. I contacted XXXX on XX/XX/XXXX and referenced that second request for my account to be removed form collections. I was informed that the collections agency denied and requested payment. I then contacted Southwest Credit and inquired about the request form XXXX and they stated that they never received any request. They took my information and stated that they would call me back. I continued to call XXXX between the dates of XXXX and XXXX to request my final statement and to request that the third party collection agency be removed from my account. XXXX repeatedly told me that they did not have to provide me a final bill and requested that I pay them the amount of {$360.00}. I informed them that I was told on several calls that I would get an updated bill in the mail. The customer service representative on XX/XX/XXXX told me that they do not have any function which will allow them to send me an update statement for the changes in the charges. I requested to speak to a manager and supervisor which they informed me that my bill was sent to collections in error but stated that they would not remove it until I paid XXXX {$360.00}. I requested a my updated statement again but XXXX refused to send me one. I then requested another ticket be generated to remove from collections but they denied stating that XXXX tickets hade been sent already. The manager of XXXX then stated that I needed to pay today or my account will stay in collections. She continued to recognize the error in billing but stated that once the bill is paid they would remove form collections. I informed her that I would submit payment once I had the ability to view my updated statement and that the third party collections was removed from my account. She stated that she would not send me the bill and that I should trust her that my balance is accurate. She reported that the collections will remain until I pay.
