Refusing to Attend to a Technical Problem

Logged a call on 29 Jan 2015 with Reuben to get a Technician to sort out very poor and erratic reception at home. Nothing happened so phoned again on 3 Feb 2015. Reuben said he will escalate the problem for attention. Still nothing happened so phoned AGAIN on 5 Feb 2015 and Reuben said he will escalate it. I asked him what difference this would make since he ESCALATED this the last time. Reuben was hapless and couldn't give me a satisfactory answer. He said he will ask Yaseen (supervisor) to attend to this. Today is 10 Feb 2015 and these imbeciles still have not even begun to address my urgent problem!!! MTN is clearly useless, arrogant and have NO CLUE about customer service. No doubt now someone will respond to this and will try and address the problem. Well guess what - too little too late!!! I sincerely regret being an MTN subscriber for 18 years.
