Without a phone for almost a week now

As advised by the call centre, I notified Vodacom a month in advance that would like to cancel my contract and convert my number to pay-as-you-go. I was sent an email on 6 March 2016 stating the following:<br> <br> \The contract on the cell phone number 08*** will be cancelled and the number will be converted to prepaid on the 31/03/2016.<br> <br> An email will be sent to you with the migration of the line to prepaid. This email is only for reference purposes and requires no reply back.<br> <br> You will be required to recharge your account with a recharge voucher within 48 hours once the number has been converted to prepaid. Failing to do so will result in the number being deleted\"<br> <br> On 1 April 2016, my phone went off-line and despite numerous calls to the call centre and what they call an \"escallation\", I now, on th 6 April, still have no phone with no network and no calcellation email.<br> <br> Vodacom, you are leaving an 8-month pregnant woman who works 40km from home without a cell phone. This is totally unacceptable."
