Mtn - Worst Customer Service in South Africa

In November 2021 I app**** for a data contract at Mtn with a router included. The device was delivered without any instructions included and I did not receive any email or other communication from Mtn. I inserted the sim card, switched on the device and it didn’t work. After 3 days of trying and failing to get any help from Mtn I cancelled the contract. I returned the device to their Menlyn store where Mr Zunnard Hammond, who helped me, assured me that everything would be taken care of. Since then Mtn has taken money from my account twice now totalling an amount of R2341.51. All the phone numbers are automated and doesn’t work. Emails are only responded to with automated replies. On their website they tell you that the best way to contact them is through Facebook messenger. Here, someone does actually reply but still nothing is done to resolve the issue. Please, DO NOT USE THIS COMPANY. THEIR CUSTOMER SERVICE IS NON EXISTENT!!!
