Absolutely Shocking

Ok first off I wantedito cancel my standard 24 month contract where the mtn service providers offered me to use their 808 service where they issue a number but I tried 3 times but nothing, absolutely pathetic! Then I personally went to the tygervally store to manually cancel my contract where I signed to go to prepaid but one the billing date (14th of each month) I received a credit to my account of my usual subscription bundle. MTN, I am addressing the CEO's and head of directory that you are involved in invalid business and its is an embarrassment to have my name as one of your \loyal customers"list"""
