Mtn problems

<p>I have an mtn contract for 50GB data a month which is capped. My new data for the month kicked in and I was only credited with 458MB. I don't know if this is just an error or what. I am waiting for my mtn sms that tells me monthly that my accounts been credited. Now I'm going to have to go into an mtn store to see what the issue is unless someone from mtn can have a look at my account for me. I always write to customer care and never ever get a response from them and I'd rather have it sorted out immediately than leaving it.</p>
