Pay R500 for Data, NO Data for 2 weeks and no one knows why???

I have been without Internet for almost 2 weeks now and MTN cant help. No one seems to know why. I have a Home LTE Router. Only today someone said i was barred from taking my router elsewhere (No one ever told me i should keep it at home, they assume its common knowledge, well its not) She said its fixed i can switch on and connect, there is still no connection, I pay R500 a month so i can work from home and the kids can connect for studies. The Grove Mall MTN Store is pathetic, I ent yesterday and they sent me packing, the lady said i have to deal with call centre as i bought this deal online, didn't even want to check on system until i insisted but she was not helpful just made a joke of my situation with her friend (Very unprofessional) I sent numerous email to and Fro and when i call call centre i get transferred from pillar to post. This is really not service at all, you don't deserve to call yourselves NO in anything. Nthabiseng Tau ***
