Cell C is harassing and bombarding the public with SMSes and call centre calls

I write this review with anger and on behalf of a dear elderly friend, as Cell C sends hundreds of SMSes daily to a friend's Cell number, enticing him to purchase additional air time, data or even to take out a contract. This week alone, just from Monday to yesterday morning, I counted 187 SMSes to his cell number, as well as numerous telephone calls to try to get him to take out a contract with Cell C. He is on pre-paid and this is blatant harassment of the most unprofessional kind. He has told the agents (always a different person from the Cell C call centre) to STOP calling him and harassing him - HE WILL NOT TAKE OUT A CONTRACT. I thought we have a Consumer Protection Act, which only allows unsolicited cold calling if the client has agreed. Cell C is ignoring this completely and bombarding members of the public with harassment calls and SMSes. STOP your nonsense - leave the public alone, especially if they tell you in NO-UNCERTAIN terms they are NOT INTERESTED.
