Artime and Datat=

Good day,<br> <br> I have been reporting an incident where by my data and airtime deplete all at the same time. Yesterday, I bought 75MB daily data and was left with R18 airtime, when my data was about 42MB it started taking my airtime aswell to the point where I was left with only R2 on my account. This has been happening for the past 6 months and no one at MTN can assist me, so yesterday I phoned MTN again, I spoke to a guy called Simphiwe who made me hold the line for almost 1 hour, I eventually dropped the phone and called back in and spoke to Simon Mabaso who was very rude to me and told me that its not MTN that take both my data and airtime but my phone and he said I should call Samsung and fix it with them. How on earth is it possible that I get a contract phone with MTN and they are my service provider but when data and airtime vanishes from my phone the fingers point at Samsung. What I want to understand is that is Simon Mabasa/MTN trying to tell me that they have sold me a dysfunctional phone and no one in MTN (as big as it is) is able to help me? About two months ago, I have reported a billing query even today, I haven't had any response from MTN. I need assistance urgently.
