November 28 2022, order #8158771407036052. I bought this item by mistake, and CANCELED it after a few minutes. Seller ignored all my messages and sent me the 2nd item ASAP. So, I paid twice for the same order. I wanted to return it and asked to send me Return Label. Recently I had heart operation and I'm not allowed to use any electrical devices- massagers because it is dangerous to me due my Medical Cardio Stimulator/heart pace maker that stimulating my heart muscle. I still have not opened parcel. I did not used or tried item which I bought and did not ordered. I sent messages to seller & Customer Service. I got link from them "500 Internal Server Error." It is NO BUYER SUPPORT. I can not communicate with Seller and Customer Service web site. It is difficult to find any help. Seller want me to check Operating Error in item, make video of it and provide like evidence. Why I should do it if I bought item by MISTAKE, DID NOT ORDERED & still have NOT OPENED PARCEL? Now What I have to do with 2 useless items? Connect & communicate with Customer Service website IS NOT POSSIBLE. They want only money from you not giving support.
