Frustration to cancel an online contract!!!!!

I went to a Vodacom store to get a contract for a pay as you go number. I was shown the demo phones on special and liked a phone that was on a double deal. I was told that this deal was only available at Vodacom Online. I phoned them and took out the contract. The phones were delivered on 26 July, but it was not the same as the phones we viewed in store. I called Vodacom Online and canceled the contract and was told the phones will be collected. It is now 10 days later, the phones have not been collected, Vodacom took money from my bank account for the canceled contract, I am stuck with phones I do not want, can't buy another contract before this is sorted, so I missed out on a Samsung S20 double deal in store that ended on 4 August 2022 because Vodacom Online did not do what they were suppose to!!!! Plus I am paying for a canceled contract!!!!!!!
