Telkom services

First of all I bought the New phone at Telkom and the sales agent ddnt tell me about the cellphone insurance option and the sim activation amount.i did pay the sim activation after the bill was sent to me, two months after I bought the phone which is February my new phone started giving me problems such as getting hot, fingerprint botton not working and freezing. I went to the store and the to report it in February the store sales person told me to go to Huawie since it was a new phone in the store, I got to the store HUAWEI and got assisted by a lady call Nhlanhla and I was told that they dnt have stock on the part that the phone needs i must wait 2weeks,i called after 2weeks still the part was not available and a month later March I went back to the store demanding help but one of the store manager said he can't take the phone due to covid19 and the stores and repairs will be closed, he made a call to the next telkom store in the mall called Menlyn and i took it there till today my phone is not back yet but each month from March they have been deducting R599 in my account, I went there on Friday again and they told me that the phone will be back next week I should wait for sms, I dd talk to the lady manager where I bought the phone and she told me that she can't do anything to assist me since the phone went to repairs,she asked me if my phone had insurance and I told her that I dnt know becouse I wasn't given the option if I wanted an insurance on my phone, I did show her the agent that help me name "letwabn" she said she is sorry that I was not given that option of insurance she can't do anything about it. I'm afraid that when the phone comes back it my give me more problems and the warranty end this December. I don't want that same phone again I want a knew phone same as the one I bought and paying FOR.I am tired of getting such treatment from telkom menlyn shop LG11 next to game shop, I'm the 1 always following then even now I'm still waiting an email I asked from the manager stating I was there on Friday 15may2020 but no notification of her email
