Terrible Customer Service

Terrible customer service received from both Carnival Mall and also the ***** department. Took my modem in to be checked as it stopped working. Was sent to Lakeside repair centre just to be told there that my contract was migrated without my consent and that is was *****ently done, they even had the wrong email address. The migration was apparently done over the phone on the 20th August. I then had to go to a police station to get a affidavit done. Sent all the relevant documents through to the ***** department on the same day. Its now the 23rd and have not had 1 call from them and nobody can tell me whats going on. I am paying for data that I cant use. I keep on phoning Carnival as I was told it will take 48 hours to migrate to my original contract but still not been done.I will never take out another contract with them. Pathetic service.
