MTN Contract

My mtn 2 year contact came to an end and I had to call the call centre to cancel it. I was recieving 2 data bundles which is 1GB from MTN and 30GB student data. The call centre agent cancelled my student data instead of their 1GB contract data. Since 3 December 2020 I've called in at the call centre no help and even went to a MTN branch and still no help. I'm very disappointed in mtn as that data was for my school work and mtn could care less. MTN has the worst service ever
