Non responsive Cell C ***** department

A **********ly account has been opened with Cell C in my name. I have called Cell C and informe them about this April as money was debited in my account without my authorisation and was told I should send my details to the ***** department, which I did and afterwards I was sent an electronic email that stated I will be contacted within the next 48 hours which never happened. Fast forward at the beginning of June Cell C went again and debited my account with R1100 without my authorisation again and I immediately called their sales agents who sent me from pillar to post and spent more than an hour on the phone because nobody could help me and finally I was told to get the affidavit and sent it to their ***** department together with my ID of which I did, afterwards I got same electronic email stating I will be contacted within 48hrs which never happened. Guess what today again these people went and debited my account with R2050 and now this is getting pathetic. I don't know what kind of controls these people have in place to allow such things happening. I'm spending time, my airtime to try sort out this mess that's not even my fault. They are call centre agents are rude and very useless and Cell C itself has a very bad service. The experience that I got from them in this ordeal left me very frustrated and don't think I can recommend them to anyone after this.
