Cellphone insurance horror

Good day Jet Team Iam honestly out of words with Jet stores. I always had a cellphone insurance with them all the years. Recently claimed for my phone, I asked the lady a phone that had 2sim slots,a Samsung branded phone and she said to me the Samsung S21 had what I wanted I then bought the phone.when I got home I noticed it doesn't have I let it go because I already bought the phone. The other issue is I wanted my cellphone insurance to continue,she advice it's no longer available. I was not happy but what would I have done poor me. The last straw is when they told me it's no longer available but they still deducting money on my account.....I honestly need clarity on what's happening
