Absolutely disgusting service and bad attitude

Have Samsung phone on contract. Stopped working just before Christmas. Was suffering with severe Glandular fever so really sick and could not stand long but needed phone. As you go in you get a numbered slip to be called. Queue had about 10 people, so feeling sick I figure I will go and sit outside and wait half an hour till my number is called on their screen as they do not have a chair for me to sit on. Wait half an hour, go back to find that they are not using the number system so i stand in queue again for 20 mins. Phone fixed in 1 day so go back and stand in queue again with a number which they don't call. 3 weeks later phone dead again, so back to shop with same number sytem so stand in queue. Takes 2 weeks this time and I am presented with a replacement phone. Still sick but reckon since I got replacement phone I won't complain. 10 days later the replacement phone dies, so I am back at shop. Girl at entrance insists on giving me a number. I tell her that they dont use system. She insists, stand in queue for 20 mins and I insist that they give me a replacement phone. They do not care. I call manager and he also does not care. This customer service = move to MTN/CellC
