Bad or lack of service from Samsung Century City Smart Care center

I took my Samsung galaxy s7 edge for repairs to Samsung to smartcare on 23 January 2018 and I have still not received it. It has been 3 months already. Every time I go there they always promise to have it done the following week. If it's not in Johannesburg, it's on it's way. The worst part is that I can't even call them as their phone lines never work. So in addition to petrol costs, I am being **** to by Samsung.

I recently reported this matter to Samsung and they requested I email them my documents but am waiting for a response. It's been two weeks or so since I have done so.

I am highly disappointed in the bad service from Samsung especially since it's a well known brand.
