disconnected

disappointed in multichoice,I always pay my subscription on the 20th, my billing date is on the 20th and for the past two months I have been disconnected before my billing date. I went to your branch and called the call center and I have been told that I Will not be disconnected but to my surprise I have received an sms today I have been disconnected because I did not pay, am tired of the up and downs and am tired of paying reconnection fee for something that is not even my fault, am also tired of wasting my airtime. Please sort out my subscription, I want my services reconnect.
