MTN totally rips off customers!

I have been with MTN for over 15 years. I renewed my two year contract on the 25 August.<br> <br> I moved from a corporate package to a lower package including the following.<br> <br> Free mins and 500 MG of data. Included I added a 3 G ****le for my laptop with 500MB.<br> <br> Last week on Thursday morning for absolutely no reason I was cut off on my 3G ****le and phone.<br> My phone bill was completed settled last month. MTN told me they had placed a limit on my account? WHY?<br> Secondly I ran out of 500MG of data and only switched my laptop on once, how on earth is that possible?<br> No apps run on my phone out of wi fi nor on my laptop. I bought another 500MG of data and this ran out in two days with my cellular data setting completely switched off on my phone.<br> <br> I am now getting sms to say I am going to be billed R2250 and when asked in teh Fourways store, she said lots of sms were sent out in error. MTN what is going on? I suggest you sort this out, many people complaining of same issue. I will be sure to move networks as I cannot buy 500MB of data every three days- absolutely ridiculous !!! I need an explanation as I know exactly what is being used on my phone and it is certainly not using such high data !!
