IT'S IMPOSSIBLE TO BLOCK 24 PHONES WITH MTN STAFF

Good day, I purchased 24 Samsung Pocket NEO's on Friday the 2nd October 2015 on your online store. i received the stock on Monday the 4th October 2015 and all was in order, I was impressed with the prompt delivery and quick exchange of goods. We therefore sold the units to a customer and whilst in transit the truck was hi-jacked and the cellphone stock was ******. This happened on the 8th October 2015, since then i have been calling in to the call center and no seems you know how to BULK block the lines. I gave up on your call center and drove to the nearest MTN store (Fordsburg). Once arriving at the store the lady who assisted me was facing the same problem whereby the agent on the other line was sending her from pillar to post giving numbers which were incorrect and she also got frustrated and said with out the call center she is powerless and cannot block the lines. I find this a bit had to believe, i have all the invoices on hand and all the proofs of payment including the case number of the crime. All i need is the lines to be blocked as they were ******, and proof that they are blocked for our insurance purposes. This is my last resort as we are having no joy with the call c
