Paid first over charge

I am extremely concerned with the current situation. <br> <br> I am being over billed for data usage which i disputed on the first over charge but allowed the payment to go through in hope that MTN will resolve and reimburse me. instead the following month i was billed seven times the first incorrect month, i.e. R 7000. I had a discussion with MTN call center on the first over charge and was assured someone would respond, a month later and no support has been forthcoming, instead my services have been cut. I have been to MTN customer centers and was told that i cannot be helped as services are down due to the strikes. I have also spoke to many people and they are experiencing the same overcharges as myself, so this is a gloabl issue for MTN. I have multiple contracts with MTN and spend a large sum month each month with them, this will certainly stop until my queries are resolved.
