Worst network Service prover - Superflex

MTN is proving to be thee worst service provider one can use. Ive been using MTN Superflex for the last few months. I have two accounts i am paying with you guys. I hardly stay long on the phone but each month i receive messages of being downgraded. I pay for the subscription on the 8th for the last 2 months. Now today around 13h30 you decided to downgrade me while i still have about 9Gig of data and have paid until the 7th of December. I need my data back and the airtime ive paid for until my next debit date then you can cancel this nonsense of yours
