Phone has been in for repairs for too long.

I have handed my phone for repairs for over a month now. after a good three weeks I was told to pay the excess fee and my phone will be repaired. I did that and a day after I was told repair is complete and my phone will be sent back to a Telkom store. I called to do follow ups and I was told the phone is in the process of being couriered, now its been a week and a half when I call I hear different stories. what ****ed me is when I called today and the consulted said she has sent an email of all the details regarding the phone only to find out that the email reads "Kindly note that your device is still being repaired , we will provide feedback soon ." I have never missed any payment but it is now a hustle just to change the battery of the phone. what is it that I am paying for when I have to wait forever to get my service. I am very annoyed.
