MTN DISGUSTING!!!

Actually very disappointed in MTN service. They are utterly unprofessional. I cant stand the bouncing back and fourth that MTN always does. I called in about 100 times and if I am not at customer care, i am though to re tensions and if not that i am through to accounts if not that im at the store. Please explain how a person is on the highest contract "Sky Sepreme" package which was done on the 14th June 2018 and only migrated in the 1st August, Which I only found out by calling every single day because my package was not working and no one could tell me why but yet I was charged for it...... I was also charged for two packages on one contract. I was told that i would be credited since August but been suspended twice in one month and been told I am going to be suspended again. STILL NO CREDIT!!!!!!
