MTN ROBBING CUSTOMERS

I had a 2 year sim contract with MTN which was offered to me during black friday 2 years ago. This ended on 14 November 2020. MTN did not inform me that any data used after this date will be charged as out of bundle. When reviewing my MTN app it did show that I have the normal gigs to use but the promotional data was over due to the contract period. I continued using the data believing details on the app, that I can use the 30gig but not the promotional data for a price of the R299 as per the contract.

However MTN did not notify me that each MB that I was using was being charged to my account. I was now billed R2,414 without being notified of the policy. I did not cancel my contract as I was awaiting the black Friday upgrade deals for 2020. I upgraded on the 25 November 2020. Between the 14 and 25 November the MTN app still showed the balance of the 30gigs for my use. MTN is robbing customers by misleading. I want a full refund of my money.
