No qualified people working at this company

If I could give zero stars I would. PLEASE stop calling me, stop threatening me with legal action, stop smsing me, lose my name, my number, everything about me. I am NOT a client of yours, my contract was cancelled with immediate effect and taken over by the new owners. PLEASE this has been going on for 2 months with DAILY CALLS DAILY THEATS DAILY SMSES! You are deducting monthly payments from me and the new owner, this is theft and *****. I will complain on EVERY SINGLE SOCIAL MEDIA channel if you do not stop contacting me IMMEDIATELY!!! Please train your accounts department how to actually run the accounts as it seems like cancellations never get done for anyone and you charge the old owners and the new owners, I have been through all the reviews and I am not the only one complaining about this. I would appreciate it if you would please sort this out RIGHT NOW so that I can stop being spammed by your calls and smses. Get a real qualified person who knows what they are doing to deal with this please.
