MTN - Worst of the Worst - No customer service at all!

If only I could give a lower rating! I have been patient and understanding but enough is enough!!!! My Mother got me a contract on her name and also gave me her old number which is also on contract with MTN. So I am paying for both. She has already sent all the documentation to approve that you can speak to me regarding the account. This is "note"has been made on the old system, but now You dont want to talk to me because you are on the new system. What bull**** is this!!!! Everything that you needed was provided to give permission so that you can speak to me. Get your **** together! My Mother forwarded the statements to me and we noticed that there is a charged on the April statement - we dont know where it is coming from. WE did not upgrade - nothing has been changed on the contract. I have called multiple times - spoke to multiple people and still nothing is being done about this charge! My latest call to a manager called Melissa said a refund would be issued, guess what nothing to date! They are just pass the buck from one department to another. Disgraceful. *** & req*** & *** & *** Get this sorted out!!!!
