USAGE LIMIT NOT SET TO 0 AS REQUESTED NO A HUGE BI

My request and explanation :-<br> I recently took out 11 laptop contracts with MTN on receipt of the laptops I specifically requested that the usage limits must be set at 0, so that I do not receive any out of data bundles billings and that I do not exceed the 500mb or 2gig bytes assigned to the specific contracts. <br> To my surprise when I went in to MTN active today I noted the following cellphone numbers under the different contracts <br> <br> 083 *** **** -R1 754.00 for out of contract bundle rate vir 3.97GB used<br> <br> 083 *** **** R 76 for 610 mb out of contract bundle rate<br> <br> 083 *** **** R801.63 for 1.074G out of contract bundle rate<br> <br> <br> In total on all of my contracts I receive 9 gb of data bundles per month<br> I still have 4.4 gig remaining on the other contracts<br> But I will be charged for 3.7 g out of bundle contract rate <br> Even though I specifically requested on receipt of the laptops that the usage be set to 0 <br> <br> Is there a possibility to please <br> 1) Deduct the out of bundle rates that I am going to be charged - from the data bundles that I still have available on the other contracts <br> 2) Confirmation that the usage limits are now set to 0 as the store did confirm via emai
