Just another failing company with poor service and delivering what they promise

I have been due for an upgrade for a few months now. A few days ago I finally had a chance to contact them to upgrade. Just for them to tell me that the upgrade was declined. How, why? They said they would investigate the matter, and get back to me the following day. I still didn't receive any feedback from them. I have been a customer with cell c for over 10 years, my bills get paid via debit order, and never missed a payment once. If this is how they treat their loyal customers, then I would want nothing to do with them. Their customer service has become poor, their network service is just as bad. they take it upon them selves just to migrate your account to Vodacom, which in my area is even worst reception. Just another failing company joining the rest of the *********** *****s that have no care for their customers, and no idea how to keep a company at heir best. CEO's *****ing money, ridiculous bonusses, and in the end left with a useless company that can't deliver what they promise their customers. But do you dare cancel your contract, and you will be penalized like there is no tomorrow.
