Mtn's misleading contracts

Good Day.

For those of you who are considering taking out a wifi contract, please be weary of Mtn's promotional deals. I had taken out a contract with a router for 20 gigs day and 20 night in Feb 2018 and i have still not received my full data but i am being billed the full amount.

I went to the Ballito store and they said that the contract was not migrated and that they would credit me on the next credited date of which they did not.

Attempted calling the retentions department numerous times to which they eventually answered and sent me an email without explaining what they charging me for and said that it will cost me R5000!.. I am not sure why i have to pay that amount for data that i will not be using if i cancel or why i have to pay so much for a router that's only R1700.00.

Mtn refuses to correct my package, credit me or cancel my contract which they have misld me into taking.

I am extremely frustrated and want to migrate.
