American Home Shield AHS Charged my debit card in less than 24 hours after i cancel order service in less than 10 minutes and the resolution is to return refund in 14-21 days, misunderstanding of another charge Memphis Tennessee

I'm so upset with this company. I've complained to them, on Twitter, BBB, AG, and now ripoff! Why? Because I feel as if their service is horrible. I contacted AHS.COM on 4/8/21 and requested service for my oven within 10 minutes I canceled the order because my husband said it was too high. On 4/9/21 I was hit with 139.06 charges from them and it wasn't even 24 hours. My problem is I CANCEL it why charge if I cancel? Why is it a cancel button if you're still going to charge? It took you less than 24 hours to charge me, but state it'll take you 14-21 days to refund THIS IS NOT ACCEPTABLE! Also, on March 25, 2021, I requested service now I pay my $60.00 a month I had to pay $85.00 for the service charge for the person to come out.. then when he comes out I pay another $83.00 WHY AM I PAYING TRIPLE? This makes no sense I would never say anything, but I feel as if that's not right after I have seen this disgusting service from them. I believe this company should be audit because I think people are being overcharged and charged several prices for what they didn't assume they would. The first time they came out I was satisfied with them.
