Zaprada Rolex Store Double Charges – Request Cancellation and Full Refund

I purchased a Rolex watch from Zaprada Store through Cash App, and the product is still being advertised on Facebook. My understanding was that there would be only one payment taken each month, but instead you have been taking two payments each month from me, and you are withdrawing from both of my bank accounts. I first noticed this double charging last month. I am 81 years old and it is not easy for me to track or upload online documents, but I can clearly see that more than one payment has been taken when there should only be a single monthly payment. I request that you immediately cancel this agreement and stop all future charges. I also demand a full refund of all extra payments that have been taken beyond the single monthly amount that was originally expected. I ask that you review my Cash App and bank records linked to the name Lois Denson and correct this situation as soon as possible.
