Bad service

My phone had liquid failure and was booked in for repairs. I paid access fee for the phone and a few days on the 20th November after paying the fee I went to telkom to collect my phone,it turns out that the phone wasn't fixed I say this because the same problem the phone had initially was still not fixed,I had to send back the phone on the 21st November for reassessment,when a called the the company they told Mr that they found liquid in the phone and I explained to them that the problem was supposed to have been fixed when I initially send the phone to fixed. I have since been getting fable stories from the consultants about,one being my phone is ready for collection at Telkom in Hatfield plaza only to find that they don't have my phone and that my phone is still being "fixed".I have called everyday for the past week to find out about my phone. I am paying for this phone and it's not fair that I'm getting the same excuses from this company yet at the end of the money they don't hesitate to take out money from my bank account to suit their interests.

Please intervene.
