SERVICE IS PUTRID PATHETIC...*********** SERVICE

So MTN suspends my account on the 28Th of February due to me reaching my call limit on my account, I then purchase 1gig of data on the 1st of march and I get my monthly airtime and data on the 2nd of every month and its the 3rd and im still not able to operate my phone, the 1gig data that i've purchased expires in 30 days which means i've lost 2 days of that already......this is a huge inconvenience. so I've called on Monday the 2nd to find out why this is the case and all they told me is that they escalating it (where to I don't know), I called again this morning and the agents tells me again \it takes 2 to 24hours for your account to be active again"its more than 24hours and nothing is working!!!! I've asked the agent to get me her supervisor and all she did was kept quiet"
