The worst service ever

We upgraded our tablet about 3 weeks ago and we waited 2 weeks for stock to arrive, At gezina chatz. We discovered that the touch screen isn't working properly. I went to vodacom kolonnade and that's where I was so ashamed to be a customer of vodacom. I waited 35 min and was helped by Siphiwe he informed me that it is the \ 7 day in store procedure "and refused to help me because we didn't get the tablet from them. I must take it back to the store where I got it from. I then asked for the manager and after waiting another 15 min I was helped by Stefan who was also not very helpful. I was then assisted by Vhathn who sorted it out as it was just a setting problem. I got great service from him and another consultant called Sanfra. I insisted that the manager get SIPHIWE to apologise and he then did. Siphiwe refused and denied that he has told me to go to gezina and also said he will not apologise. The service I received today was pathetic and I really feel ashamed to be a vodacom customer because that is not the way to handle loyal clients who has been with Vodacom for almost 20 years and has 4 contracts with them"""
