Absolutely terrible shocking service no response from MTN !!!

Ive been trying to get hold of mtn cancellations for weeks now . First it was the excuse I can’t get through because it’s month end ? Then the excuse because it’s month start . I merely want to know the cost to cancel my contract as I’m going overseas . And want to know how much I must put aside to cancel before I leave ? Is there nobody that can do this calculation for me ? The service is SHOCKING ! Still waiting days for Nadine the manager to call me ? Managers are always on phone calls with other clients ? Come on man. Must I not pay the contract to get MTN to hound me to pay and then I can get someone to assist me in cancelling ? Please GET HOLD OF ME i want this issue sorted. I would not recommend MTN to anyone ! I have done the retention’s email. No response . I have done the fax . No response . What else must i do !!??? I call in I wait I get transferred from pillar to post ??? I want to pay you square and your cancelations fees etc ? Do you not want me to pay you ??? PLEASE Somebody at MTN assist me .
