MTN Contract data ******* - Need to cancel this contract

I bought a Phone on contract (Huawei P40Pro) from MTN. They didnt indicate that the contract option that they helped me select on their instore desk top is majority educational data. So every month im sitting with 1.5 Gigs of educational data that cannot at all be used because im not in school and its not my area of interest when it comes to my phone. I had stopped using MTN since 2014, i regret going back and will encourage anyone to think twice before going to MTN. Their offering is not meant to be an equal give and take, their packages and service offering are directly meant to ensure they get the most out of you while providing the least value. If they think this is the end of this, they have another thing coming. No wonder their customer ranking went down
