Cell C worst network to use because of customer service

I am absolutely discusted with cell c network provider. If you are planning to use them as a network provider I suggest you go to mtn and telkom at least you will get proper service. I have been with cell c for 10 years and have to contracts with them I have never delt with there customer service or sales department over the phone for the pass 10 years everything I did was in store but after the experience I have had with there agents on the phone I am mortified by the treatment I have gotten. They have no loyalty ethicate towards their loyal customers and there agents are so rude. I have had the call hung up on me for about 20 times in one week you might think I'm exaggerating but every time I call in and explain my issue it's like they don't no what to do so they hung up so each time I call I have to explain over and over again and then they hang up on me. Every department blames each other no one takes responsibility and they even transfer me to a close line. I can't wait to have my contracts with cell c sorry to say but I will rather go to a company with good customer service that show loyalty to there customers then be with a company for 10 years that can't resolve a simple issue that was there mistake in the first place. Disgusting reay the owner of cell see should really go and investigate the call centre's because they will be loosing alot of business through their agents. And the worst part is they do not have a complaints department where you can make a proper complaint.
