Poor customer service from Telkom Mobile

In February 2016 on the 6th, i took out cellphone (Huawei P8 Lite) contract with Telkom mobile at one of their work in stores at Northgate Mall. I got the phone (***) and also requested to port my old number from vodacom to Telkom ***). It was on a Saturday, I stay about 1.1km away from the mall in Northriding (52 Felstead Avenue). When i got home, i charged the phone overnight and only find out the following day that i do not have a signal coverage at my place residence. i then went back to the store around the 10th of February to raise my concerns and inform them that i'm not getting coverage at home and would like to cancel the contract as it was still within the 7 working working days for the cooling-off period. However, the consultant advised me not to cancel yet but she will log a call for me with their technical department to send someone to come and test the signal coverage and that they will not debit any monies until the issue is resolved and technical guy confirmed that there is no coverage(Case No ***7) and that would be within 72 working but 10 working days passed and no one called me still from Telkom. I then decided to go back to the store on 22 Feb 2016 again to now cancel and hand in the handset. i was then assisted by a consultant by the name of Nelly (whom by the way stays in the same address as myself and knows the coverage is very poor) to cancel the contract. I filled the cancellation form, went through the cancellation procedure and she took the device as well and then she said would forward the request to head office or cancellation unit to processing which should be finalized within 21 working days (Case No. ***2 or ***). Fast forward 31 March 2016 (12:13) They debit around R450 (which it was then reversed), i called the call centre (081180) to find out the feedback regarding the cancellation request and also why are they debiting for the service i'm not getting and spoke to gentlemen by the name of Mongezi mavimbela and to my surprise he told me that the status of my case/query shows as pending and that it was dispatched to a wrong queue and promised to forward to the relevant department and escalate the issue to his manager and that i would get feedback within a week and also that someone from the technical department would still call me to do the signal testing but two weeks passed and still nothing and had to give him an alternative number ***)as mine is not active. On 15 April 2016 (13:13), i called again for feedback after they debited an amount around R680 (which i reversed again) and spoke a female consultant called Sentle, which i had explain my story again and request a feedback but she also told me the same thing that my request was dispatched to he wrong queue and promised that contract will be cancelled by the following week and will also escalate the matter to her manager (***) but nothing happened. On 21 April 2016 (15:18), i called again for feedback and spoke to Portia but had no feedback as well and had to explain the story again and she wondered i should pay for the service i'm not getting and then requested me to email her the cancellation form i completed i completed at the store and she will take it from there and escalate the matter. And that on her side it should the cancellation was put through on 01 April and will be done within 21 working. She provide me with with her email *** and promised to email it to her, which i willdo on Monday. She told me that someone called me on 04 April 2016, probably from the technical department but they called on my next of kin number *** and not on the alternative number i provided to Mongezi mavimbela on 31 March. I really need this matter finalized and would also request that i get my old number ***) back as i really need it. If it can please be converted to prepaid. I don't seem to be getting any joy from Telkom and their complaints department seem to be non-existent. if this matter is not finalized in the next 7 working, i'm taking up this matter with ICASA.
