MTN Business Upgrades - a **** Upgrade

We were informed by MTN business that we could upgrade our 2 lines. They processed the upgrades but there was a mistake on the device, it was reversed and the new devices were processed. January invoices arrived and there were triple charges for devices. We queried it and were told these were charges for the old devices until the contract was finished. At no stage were we informed we would still be charged for past devices, this is not the way upgrades at MTN have worked when your contract hits the 20th month. Literally out line prices have increased 3 times, this is simply not possible or feasible for anyone to afford. We have logged series with out MTN business Rep Bronwyn Cooke and Uvisile Madikazi as well as through the MTN business help desk and the Meadowdale MTN store with Lukas Mphela the consultant who assisted us. The feedback we ave been given is that MTN is allowed to double charge to complete the past contract. Honestly I am shocked. MTN - you don't serve your customers, you just serve your profits.
