I am being charged interest on a buy now pay later account which shouldn't have interest. I have nothing on take 3 account and still receive invoice asking for minimum payment or take 3 amount of £5 each? Have tried paying these to stop interest & still they charge me? Emailed customer services 1 week ago. Got generic e-mail stating that I would be contacted in 24 hours, still not had a reply. Sham customer service.
