UNSUCCESSFUL SIM SWAP

i recently lost my phone and i needed to do a sim swap for obvious reasons, i first went to a MTN store to try and do the swap however i was told that i need to contact mobile plus for them to activate the swap because i had the 1 to 1 contract with them. i then called mobile plus and i was told to buy a blank contract card and call them back with a sim number for them to initiate the swap, i then did that on the 13/10/2015 and the consultant informed me that the card should be active within 24 - 70hrs i accepted that because i really need that number back however till now my card is still not active and this is after making a follow up call on the 19/10/2015 and was told that it has been escalated on the system and there's nothing else they can do, i just have to wait. what saddens me the most is that month end will come and my account will be debited for something that i don't have access to. A speedy resolution to this matter will be greatly appreciated as all of my accounts have this number.
