The left hand doesn't know what the left hand is doing- never mind the right!

A Cell C customer for decades, I am bitterly disappointed with the service I have seen during a contract upgrade , and what has happened since. Upgrade information that was emailed to me was incorrect, according to one of the many agents I spoke to in the past week. Now I cannot make calls although I have 426 minutes of calls available, and I cannot use the SSD code services either (service barred). 4 calls to customer care on a Saturday morning, with 1 call transferred to cancellations- and nothing will (according to the agents) be done until Tuesday. Goodness knows what ****-ups will follow with the cancellation! Wholly inadequate resolution systems.
