3 weeks after cancellation no Pickup of handset

I telepathically took out a new contract with Vodacom and within the 14 day period I decided to cancel my Contract - Date of Contract 17 Feb 2015 cancelled 25th Feb 2015 and requested they collect their phone and made numerous calls to Vodacom ***4 for collection, only excuses they have asked courier to pickup the phone its now the 18th Mar and that's not all I also was told initially no connection fee of R97 but they charged my account and I've been told a credit note has been passed. I was told that phone will be collected within 2-14 days still no luck
