I've cancelled my contract with vodacom

Good day,<br> <br> I am not very please with vodacom because on Monday 06th July 2015 I've app**** for the new contract (USB Moderm) R149X12 with 2GB of data for 12 months, the account was approved over the phone and the package was delivered on my work place on Wednesday 08th July 2015 around 10:30am. On my lunch time (13:00) I phoned vodacom to activate my new number for the moderm which was successful & the consultant told me it will take around 5 hours for the sim to be activated, got home around 20:00 switched my laptop on and tried to use the moderm but the moderm was unresponsive. The next day I phoned vodacom to cancel my new contract over the phone which was done successfully and the consultant arranged the courier service to come pick up the package which they did come the next day on Friday 10th July 2015 to pick up the package, this morning (Tuesday 14th July) vodacom debited R212 out of account, how can the deduct money if I don't have the package with me??? I need my refund please because I've cancelled my contract with you guys.
