False sales

In the beginning of January 2022 I received a call from blue label connect offering me a cellphone contract upon speaking to the sales agent i asked her to describe the phone that she was telling me about as I was not fami**** with it....she told me that the phone has a finger print sensor and that it looked exactly like the Samsung A21s I agreed on taking the contract.7 days later I received the phone and to my surprise and disappointment the phone was nothing like what I expected not even close, I then contacted blue label connect and explained to the agent that I don't want the phone as it is not what was sold to me on the phone I was told that the phone will be collected and I will not be charged for cancelation as the phone was not what I wanted and that also because I called Within 7 days all this happened during January I then call after 14 days to ask why they have not responded me and why they have not collected the phone from me, I have been calling them every other day and they kept telling me their manager will get back to me and I'm still waiting...to my surprise they debited R389 from my bank account and I had already canceled our agreement as I felt they **** and gave me false information regarding the cellphone...please help
