Mtn n1 city

Today is my 4th day waiting to be assisted on Saturday i was in vangate mall mtn for 45 minutes no consultant acknowledged their clients or informed us about any system issues i left the store, on Sunday i went to n1 city branch did the application and was told to wait for the call i received an SMS to say that i was approved but until today I received no call i decided to go into n1 city branch yesterday i stood for 1 hour and at 18.57 the consultants with attitude told us they cannot help us due to system issues.. my question is why advertise a service if u cannot deliver the service was putrid should i take my money somewhere else? I work in an environment where we are client centric i understand system issues but communication is key!
