False Information

I got a call from a sales agent from MTN . She asked if im interested im getting a cellphone contract and I agreed. She said I qualify for an iphone 13 ans I agreed . She even made me to accept a debit order through my app. Was told it was going to be delivered to me . All to find out its a Sim card only contract. Have been callinh them to cancel this contract because the agent **** just to get a Sale but they have not canceled amd they taking my money
