Dissatisfied with the service of Telkom

Last year I took a HUAWEI P10 Plus contract phone IMEI No: ********** ********** 1 on September 21, 2017 this phone started to give me network problems and the screen was broken. I sent it for repairs at a Telkom store in Clearwater on the July 6, 2017 and I was informed that they will send it to Huawei for repairs which they did. The phone was repaired at it was sent back to me. I've only used the phone that was repaired only for a month last week on Friday the phone the phone froze and the screen wasnt working at all. Mind you at that time I was in East London and I did not have a phone to use. I took the phone to a Telkom store in East London Hemmingway so that they can check what's the matter with the phone. The technician that was assisting me advised me that they need to send back for repairs. At the time I was due for an upgrade and I did not have intentions to renew my contract with telkom at all. I was forced to renew my contract with telkom due to the fact that I did not have a phone and I needed to communicate with my clients and also with someone that was going to fetch me from the airport. I renewed my contract no Sunday the 12th of August 2018. When I was back in Johannesburg on Tuesday I took my phone back to Telkom store in Clearwater for repairs. To my surprise when the technicians tried to book my phone for repairs the system did not allow them to book the phone due to the fact on their system it still shows that my phone was still on repairs and it was not clear. The technicians opened the phone that's when I realized that the phone that was given to me was not the phone that I bought. They gave me an old phone that was discontinued last year and it's IMEI number is ********** ********** 6. What amazes me is that when I went received the notification that my phone was ready for collection it never communicated that they struggled to fix my phone and they have decided to replace my phone with another one. Secondly I have to take a contract that I did not have intentions to renew due to inconvenience. The worst part I'm still paying for the contract of the P10 plus. I want telkom to cancel the contract of the P10 Plus and I'm not willing to pay any cancelation fee. I will only continue with the new contract that I took in East London
