NO COVERAGE NO SUPPORT NO SERVICE

I cannot receive any better than 'edge' signal at my premises indoors or outdoors. Sent through a query to MTN on Wednesday 14 January 2015 reference number ***, received a response from Shereen Motale MTN National Quality and Coverage Help Desk 6 days later from query date, her response was 'When did the problem start', i responded accordingly and she sent back \Coverage query logged with reference number ***"7 days after the query date. I then sent her a mail asking if anything has been done about my issue"
