33 WORKING DAYS WITHOUT A RESPONSE

Tried to upgrade online. Website gave error. Phoned Call Centre assisted upgrade telephonically. Phone arrived is 32GB and current one is 128GB. Phoned the Call Centre were instructed to return phone to nearest MTN Store and phone back with reference number. At the store were instructed to go to specific MTN store. Spend more than an hour booking in the handset on 1 November 2019. Called Call Centre with reference number. Instructed 7 to 10 working days to upgrade differently. Since numerous calls were made without any success. 12 December someone phoned me saying they will reverse the upgrade so we can upgrade in store by Friday 13th. 18 December - 33 working days later and nothing. No reversal. No one know what we talking about. After 20 years with MTN I find this shocking service!!!!!!!!!
