MTN's deceiving and conniving promotions

MTN has deceived the public , again! Offering a special before Mothers day, as a mothers day promotion, and now different agents give different version of excuses: 1. "There is no such promotion" ; 2; The promotion expired a week before it was even advertised" ; 3. They just don't bother replying to email enquiries. BUT: The promotion is still advertised online.....***! MTN, I am disappointed , again, of your lack of respect for your long supporting clients and not honoring your deals.
