Useless service provider who does not care about customer service

<p>on Saturday day 22 July 2017,I had 112 of airtime ,when I tried calling few minutes after checking my balance it said "you have insufficient airtime to make a call" I Called Mtn and spoke to Vuyiswa and she said She can see that I had the airtime airtime but she said my auto updates were on and the airtime disappeared...she said there's nothing they can do for ...Mtn is always robbing people and it's annoying to have a contract with a provider that doesn't care about its users....all they ever say is that they will investigate......</p>
