BAD SIGNAL!!! NO HELP!!!

On 2015/05/28 I contacted MTN Coverage on *** regarding my complaint that I don't have any or little signal where I am staying at Boskop farm near Goeiehoek station. (Jim Fouche road) *** was given to me. I also need to explain that I provided them with the train station because I am staying on a farm and GPS coordinates are difficult to obtain.I was also informed that a technician would phone me the same day and that an email was already sent to him.On 2015/09/17 I phoned again and spoke to Ruben where after I was cut off. When I phoned back I spoke to Nhlanhla who I explained my problem to but without any success and the phone was dropped again.On my 3rd attempt I found Ruben who explained to me that the technician (Bovan Tazvinzwe) explained to them that the tower near me was upgraded and there is no problem. Since 2015/05/28 No technician of MTN phoned me or visit me at my home to ensure that I get the service as promised by MTN. No employee of MTN ever visited me to try and solve my Problem.I am tired of hearing excuses that the technician is on the road and that the problem was solved without me even been notified.I really don't think that MTN should change
