Service not where one would expect from Cell C. Just another company not interseted in its own customers.

21 Years. 21 Years I have had a Cell C contract. Phoned the call centre to find out why my contract increased by 35% month on month. They CANNOT confirm my details. I am not me. I have to verify MY information and call them back? I am not allowed to know what information is incorrect. What changed in 21 years? I cannot be assisted - and work on your customer treatment - we are paying customers by the way.
