XXXX XXXX reported to TRANS UNION that My account was LATE and in their COLLECTION Dept. 

I was in the midst of a dispute with XXXX over a {$300.00} early termination fee since I was told by a XXXX Customer Service Representative that the cancellation fee would not be imposed since I notified them I wanted to cancel HOWEVER wanted to keep my same home telephone number which may take 7 -10 days to be released. 
The trial period was ONLY 14 days, I called on day 13 to cancel but was told I would not be able to keep my number unless I waited until XXXX released it. 
Thus it would be impossible to terminate service and keep my number ( which I 've had for 23 years ). 
A few days later when i received notice that my number was released I terminated service. 
I received a statement stating I had service for more than 14 days and therefore I would be charged the {$300.00}. 
I spent countless hours trying to speak with representatives and get XXXX to investigate the rep. who assured me the cancellation fee would not be charged. I sent XXXX letters to XXXX disputing the charge. 
Without a XXXX party or fair investigation, XXXX assigned my account to their Collection Dept. 
I disputed the wrongful tactics of XXXX. Preventing me from canceling within 14 days and keeping my 23 year old telephone number. 
XXXX claimed the rep. did not enter the comments into record and therefore the agreement to charge my was valid. 
XXXX should not be able to report my account as in collection while I am disputing the charges. The also should be required to have a third party investigate since XXXX simply denied their representative had told me or had the authority to tell me the early termination fee would be waived while awaiting the release of my home telephone number. 
I have paid IN FULL my account including the {$300.00} and XXXX still refuses to enter a new report to Trans Union without the indication that it was in collection. 
My credit score has suffered, dropping over XXXX points. 
IT is the ONLY adverse information on my credit report. 
Trans Union refuses to remove the collection designation even though it is paid. 
I told them it was reported while I was actively waiting for XXXX to investigate. 
Trans Union " investigated '' and a letter arrived showing that XXXX still shows it was in collection and thus it will not be removed until 2019! 
I want Trans Union to remove the Collection designation.
