Bad Service

have been trying to migrate my contract with Mtn since September 24 to date with no luck.I have about 3 reference numbers which I spoke to various call center agents who have no idea of turnaround times the ref nrs ***...which I was advised query takes 48 hours. .but later called spoke to Gregory who confirmed it takes 7 days and promised to call me back and he never did..I made a follow up again on sunday 25th new reference was provided ref nr *** the lady I spoke to said they escalated the matter to retention department.I must now wait till Jesus comes before my account can be migrated to prepaid I feel like im being held hostage as mtn is busy recharging my account while I asked them to cancel my contract.
