Data Connection

Renewed my contract at the beginning of April. I wasn't connected to the network correctly and as a result, I'm not able to connect to the Internet via my mobile data. I have logged the matter twice, have stood in queues at MTN stores for a total of 8 hours, have been put on hold on the phone for a total 2 hours, and 2 weeks later, I still have had no feedback and no resolution of the problem.<br> The last log number is ***.<br> No-one I've spoken to has any authority to put me in touch with someone of authority.<br> Why am I paying for a service that I'm not receiving? This problem is hampering my ability to conduct business as my phone is used as a business tool every day. MTN's debit order goes off my account every month without any problems, but MTN are in breach of their contract and are not delivering what they've promised to deliver!
