Poor Service

I have an existing contract with Telkom of R199 & received an excellent service when applying the first time, I then app**** for another router contract of R199 on special in August but have received the worst service ever. Firstly my contract was never delivered to me after several calls made to Telkom they tell me that it shows delivered on the system & that the contract has been activated. The first month I was billed for both contracts but was never contacted to explain to me if they are resolving the issue or not I then received case no.s ********** 2, ********** 9 after several calls but still nothing has been resolved. After being billed the 2nd month with no feedback received I decided to reverse my debit now my 1st contract has been suspended they want me to pay the double money back to activate my account. I am not happy about this because what guarantee do I get that my money will be reimbursed.
