Bad Service Cell C

i am not impressed with the service I am receiving from Cell C. I was in arrears with my account for 3 months, end Oct 14 i paid up the outstanding. I was told my no's *** & *** was reactivated and i needed to go to the nearest cell C store to make new simcards. i requested their reactivation dept to debit my FNB account monthly. the person on the other side took my details and confirmed that as of the next month it wud be debited. They neva debited my acc and in Jan 15 my phone was blocked. i enquired & was told i never paid my account. i said that i had requested my account to be debited. they said it did not reflect and i was in arrears of +_R 3000 & +_R 1500 on the other. i was shocked as my normal instal is +_ R423 & R121 respectively on the accounts. on enquiring i was told that my account was uncapped. i had capped my accounts when i started the contract and never requested it to be uncapped. i was told an investigation was taking place. I never got feedback from them & continuously phoned them. On my last call i was told to go to the store to fix it as they cant find a recording. dont know if it will help. need assistance urgently
