Cell C service: 95% hype - 5%delivery

What is it with Cell C? Is it that the executive can't sort the company out and it filters all the way down or is that the service at the bottom end remains so ****py and it filters all the way up? Service? Puhlease!!!! Yet again Call Centre agents (Customer Care and Technical) can't give answers - this happens 95% of the time in my experience. Today, needed to do a data share and couldnt connect to account in their web site for two of the 3 numbers that have been registered with them for > 10 years. Besides trundling out all the usual and useless suggestions (have you tried using the sim card in another phone? - which i refuse to do - we're in the 21st Century after all!!!!)) I was told firstly to reset my password and then that the system showed that the two numbers were not registered and that I'd have to re-register. Agents couldn't answer why my registered numbers had got "lost" and I reaced the conclusion that agents (technical especially) aren't properly informed of system issues. Eventually sorted myself out via the App but no thanks to Cell C
