Charged after cancellation

After reading some of the complaints on this platform, it is quite clear that Tracker is well known for 1. Not updating their systems. 2. Terrible customer service. 3. Over charging customers!<br> <br> After cancelling my contract and paying the settlement amount, I am contacted after 4 months by lawyers advising that I now owe anothe amount. I called in to Tracker and I was told that there is notes on the systems indicating my cancellation (then I wonder how they could give me a settlement amount). I was then told that due it not being cancelled, I still owe an amount. I was then told that it was subsequently closed on 18 September 2015. I then requested to have proof of the cancellation, to which I was told to wait 7 days, as this is how long the process is for the Retentions department to action a cancellation.<br> <br> I then advised that am not going to wait for 7 working days as I app**** for credit and was declined due to them listing me! I requested that a Manager call me back. It is 24 hours and I have not even had the courtesy of a telephone call. This is pathetic service, for such a well renowned organisation!
