Cell C customer service sucks!

I have been with Cell C for almost 6 years now. Upgrade done on my contract as it was upgrade time. Today is the 16th of the month. I have made contact with Cell C client services 4 times up until now as I cannot make outgoing calls on my phone. Every time I am told that the matter has been escalated and that the technical department will come back to me in a few minutes. Today is no different. I contacted them at 08h00 this morning, as yet at 14h20 I have received no follow up or feedback. This is just poor service. Do not believe the ads, they are not so great as they portray themselves. Their ratings with me has dropped so much currently that I would not even recommend them to anyone I no, much less sing their praises for good service( there is none at the moment - and please do not use Covid as an excuse)
