MTN **** artist!!!

I took the double deal, Huawei 11.5 cell phone with the free SIM but now they charging me R429 for the past 3 months!!! I've been phoning their billing department to rectify their incorrect billing.I have been phoning them for the past month and got different reference numbers saying that I have logged the call. The consultants have been saying, they are going to credit me with in 7 days and yet another month have passed with the incorrect billing😡. The say a numerous customers have complained and that have taken the same deal. They say apparently, they going to do mass credit 🤷 but in the meantime they still billing me the incorrect amount 🤷, which means then, we you have to wait another month for another mass credit 😡. MTN have very poor customer service 😔 None of consultants are helpful, empty promises. MTN is just a name, faceless company without anyone 🤷 that can really assist you 😱 I must keep on reversing my money and pay bank charges, MTN charging you penalties not of your fault 🤷 your rating is dropping while they making millions 🤷. Never take a contact with MTN and hiding there additional fees, dishonest service provider 🤙🤙🤙
