PSD packet not activated

I just checked my data charges for the last billing period and noticed my data bundle was never activated,resulting in a high psd charge. I first checked with the call centre and they claimed I had app's or auto updates causing it.<br> I then checked my current billing period and noticed that I was being charged out of bundle charges even though I should have had a recurring data bundle, which seems that it was never activated since my upgrade on the 6th june 2015. so my first invoice since my upgrade is completely out of line with my normal monthly spend. I suppose I would have to foot the bill for the service providers incompetence. So after 18 years with mtn it seems I just lucked out with the \bitter connection". If mtn does check"
