Mtn service consultant drops the phone on client

On 30/03/2016 between 19h00& 19h30 i contacted the mtn service centre from a contract phone numbet ***, after holding for over 25minutes i finally got through to a consultant. My issue is wr never have good reception in our area nor 3G network. We found this odd as just a street down from us they have full 3G network. My brother & i both tried to explain this to the consultant but bcoz of poor reception she complained she couldn't hear us. Now this was our exact complaint an issue we have been dealing with since October 2015. She had no patience with us & i find it rude that you drop the phone on a customer & never bother to call back despite the fact that she had taken my prepaid cellphone numbet down which is also on mtn. Is this the general attitude mtn has to reception & network complaints. My whole family has been on the mtn network for more than 10years. This is utterly unacceptable to us that in a household with more than 5people who live with a disabled person incase of ermegency we might not be able to make a call
