Empty premises and no action makes you lose loyal customer

I'm now sick and tired of being sick and tired of empty promises and no action from MTN. I've been complaining now for several years about the MTN Bathurst tower and no permanent fix is done or help on your side yet you expect me to pay for services I cannot use and want me to spend more by phoning and use of services. Are you stupid or what, my using of your services is directly coupled to signal strength, if I don't get signal or the signal to weak I'm not going to waste try calling to get dropped calls or failed Web page downloads. My one contract is way overdue for renewal but since my other contracts are soon to be end of their terms you've turned a very loyal happy customer that advertised how great MTN were now into a extremely furious disappointed customer that will spread their disappointing experience to whom will listen and will be now looking for another service provider. They as happy customers will advertise your company for free but an angry disappointed customer will run you to the ground. So make me happy.
