Untrained and Unprofessional

It has been about 8 months since i started doing business with MTN.

At first i would have nothing but good things to say about this service provider, but as time went on i have received more problems with them then with any other provider, 8 Months ago i took out a contract with MTN for the Huawei P 9 light, as most of you know it is a duel sim phone, but to make sure of my facts i asked both the shop assistance's that helped me with my application if i could put in 2 sims even if one was from a different service provider. Multiple times they assured me it was possible, until a month ago i never needed a second sim but when i finally did i could not fined the settings for it on my phone. To my shock and disappointment the MTN Call center informed me that they could not help me and advised me to Call Huawei, so i did where they informed me that MTN do not allow a second a sim-card in there Phones. Calling MTN back i asked for answers as this was not what i was told when when i took the contract, there only replay was "Sorry about that"?? I also received problems with my Huawei WiFi-Router as first the data was not loaded, then they could not help me with connection problems and again i only to receive "Sorry, maybe you can try a Huawei shop?" I am unsure if i want to continue supporting a company that has no knowledge of there own products and have unhelpful employees. i am extremely upset at the amount of time and money I wasted thanks to a company that do not pride themselves on the costumer but rather the money they can make off unsuspecting victims,
