MTN - ignoring rural subscribers?

MTN's reception in our farming area has gone from bad to worse to shocking over the last six months. At present if I want to make a cellphone call I have to stand outside, ensuring that I am on a windy corner of the house - bad enough in summer, but it is getting chilly now! A few weeks ago I recorded a complaint with MTN, spoke to a nice young lady who promised to get back to me....well, that never happened, and the service is as bad as ever. Calls go straight to voicemail and the messages sometimes take hours to come through. The frustration when dealing with business matters is immense, and we really struggle to keep up with friends and family. This is compounded by the fact that our area Telkom landlines have been ******, so cellphone communication is our only option. Please pay us some attention, MTN! We are certainly not the only ones out here who are battling with poor reception - your rural clients really deserve a better deal.
