********** upgrade

An upgrade was done on my name without me being aware of it. I am located in Western Cape and I was told by an mtn agent that it was done in Eastern Cape, in a mtn store the date that the agent also said the upgrade was done were on 18 June 2021 but it was in April when I phoned them. I was billed extra due to the upgrade but it was promised that nothing will happen to my debited amount. It is now almost 3 months that I am waiting for a ********** case to be resolved. I was engaging with 8+agents since April with no luck. My actual contract was due today 18 June 2021 but are unable to cancel due to the open ticket.
