Disgusting disappointing service

These people renewed my contract without my knowledge and claimed their consultant did advise me. Their calls are recorded however when i asked for those recording they keep saying they still waiting.I have requested for 3 telephone recordings in which 1 of the calls i made and two were from these people and in those there better be information stating the month to month contract after it reaches 24 months and the amount. Their service has been nothing but a disgrace. I checked my credit score and im on arrears because of their neglegence. I tolerated the disgusting service for 24 months which i had issues and nobody was available with solutions. Nobody gave me feedback to why there are delays but timelessly i have received calls from debt collectors.
