Non-Existant Customer Service

This is becoming the worst experience I have ever had with a service provider!!!! Debit order bounced due to an issue with the bank, so my line was blocked. I did an EFT payment and sent proof of payment from bank site. Emailed proof of payment to Customer Care and Credit Control as well. Sent 6 mails since 26 Oct 2017, till date, no reply or even acknowledgement of receipt!!!! Customer Care line ( ********** ) does not work, i keep getting a recorded message to contact Customer Care on 084 140, which is the number for Cell C Customer Care. Suprise, they can not help me because my contract is through Glocell. Totally pathetic that Glocell only has one contact number, and even more so that it doesn't work. Will surely be taking to social media until this issue has been sorted!!! Pathetic!!!
