Autopage making life difficult

We were on Nashua Mobile and were automatically moved to Autopage due to being Cell C customers. We went to the Cresta branch a couple of months back and asked them to cancel my wife's contract and move her onto prepaid. However, this was never done (we suspect the branch never recorded it on their system). We then requested on the website that Autopage call us to sort out the cancellation of the contract. They never phoned us back but went and cancelled her phone number instead of just the contract. If Autopage had just contacted me when requested, they would have known not to cancel the number but only to cancel the contract. Now no one from the branch or head office is willing to accept responsibility for this mess up. Autopage, please just accept responsibility and move ahead with the reactivation of my wife's number as she is now sitting without a working phone. I phoned the call centre at 1pm on 28 April and spoke to Mpho Makgoa who said they would e-mail the branch manager at Cresta to sort it out. The branch manager has come back saying they don't have any record of this, which they won't since they did not record it.
