Cancellation request not logged

I placed an order on Vodabucks on 15 May and yesterday morning I called 082 129 and the guy I spoke with told me that he logged a request with the back office to cancel my order. I called this morning to confirm that it was done and the lady I spoke with indicated it was logged. I just received an sms indicating my device has been handed over to the courier. I called back and spoke to Boitumelo who advised a cancellation request was not logged and that he would log one. Asked to speak to a team leader and he hung up. Plz assist soonest!
