Phone repair/ cannot use Telkom network

<p> I had issues where I have full signal on the phone and once I try to make a call the signal just drops, so I am almost never able to make calls and when people call me even if I have signal it goes to voicemail. So I booked my iphone in to Telkom Rosebank Mall about 3 months ago now. They assured me the phone will be done in less than 2 weeks, it took around 4 weeks, the phone came back and they could not give me a report on what was fixed on the phone but I was told to check it over the next few days and see if if the issue was resolved. I had exactly the same problems. I then went back to Telkom Rosebank and asked for the report, they had no report nor could they get one from their tech team. In the last 2 months I have been going to the store around 2x per week to get this sorted. They have done 3x simswops, called the tech department and explained the problem again and again and still I dont have a working phone. They then said that their team will monitor my phone and sim remotely and they will get back to me in 72hours with a response, 1 week later I went in and the issue still was not attended to. Finally I was able to speak to the manager called Heather Webster, she told me that they can only replace my phone after it has been booked in 3 times, I explained to her that by the time I had done this my warrantee will be gone already. After numerous discusions with her I asked to speak to her manager and finally I got the number of the area manager called Gordon. He advised me to book the phone in and he will make sure that the process is very quick as I explained my unique situation and that Telkom was to blame for all this. Now today 1 week later I finally get an sms saying my phone was booked in at the repair centre. I tried calling Telkom the entire morning and had no answer, called Gordon and he only answered the thrid time and was really rude over the phone. He said that he will look into the matter and his team will get back to me. </p>
