Feeling defeated by Telkom

I am an extremely patient person, but Telkom helped me find out where my patience ends . In 6 months I have entered a Telkom store 18 times! Where there is always a queue. My issue is that no one can phone me since I got my new phone (isn't that the actual point of a phone). I will give it to them that 4 of my 18 trips someone tried to help me, yet were still unsuccessful. The rest were so rude to me and in the end they just send me away after hours of waiting and say they can't help me. It's been my worst mistake taking a contract with Telkom as I'm in the contract for two years (which they are happy to take my money each month) and I'm stuck with a phone that nobody can phone without a single solution in sight. I am feeling so defeated...
