VODACOM REFUSES TO CANCEL CPNTRACT AFTER I REQUESTED IT THE DAY AFTER I RECEIVED THE PHONE WHICH WAS NOT DUAL SIM AND I WAS NEVER ADVISED THEREOF

I have been trying to cancel my contract with vodacom since last week Friday (i feb) and still no luck! I received my phone last week thursday (7 Feb) and found out that it had no dual sim as i thought it had. I was never advises of the fact that vodacom blocks off dual sims. I then went to their Cresta store to first try port my mtn number onto the contract and was not able to and i then requested to cancel my contract because i cant use the phone and i need it for business and would not be able to use the contract sim. The sales person then called the ONLINE support for me and i spoke to an agent who assisted me and told me i dont have to pay any cancellation fees because it is in the 14 day period and that the courier will pick up my phone. I followed up on Tuesday(12 Feb) and apparently no cancellation was logged. I requested a cancellation again and confirmed my address to pick up the phone. Wednesday (13 Feb) same story and i confirmed everything again. TODAY (THURSDAY 14 FEB) SAME THING!!! TOLD ME NO CANCELLATION WAS LOGGED!!! Why is this so difficult! WHY IS VODACOM DELAYING THE CANCELLATION!!!!!! I requested the CEO's details and still dont have it. I WANT THE CONTRACT CANCELLED AND THE PHONE PICKED UP AS I REQUESTED THIS WITHIN THE 14 DAY PERIOD! IF THIS IS TOO DIFFICULT GIVE ME YOUR ONLINE WAREHOUSE ADDRESS AND I WILL TAKE THE PHONE THERE MYSELF!
