We have sent them multiple cancelation emails they just keep debiting my account evry time you phone them and ask why they are stil debiting the account thy conveniently some how did not receive any cancelation email . The first cancelation email was sent in 25th of jully 2022 at 8:28 then the next cancelation email was sent on the 20th October at 10:01 of wich all the proof is kept but before that i canceled thelephonicly between the 21st and 24th of March 2022 . I conser that as fruad and theft and should i block the debt oders from my bank I would most likely be handed over to dept collectors.
