Worst experience ever

I bought couches and a bed on credit I was double debited in November requested a refund on the same day 20th, they've been giving me run around I called more than once, emailed 3 different emails, sent a whatsapp to the consultant lay a complaint but there is still no refund or proper feedback. Their consultants have a condescending tone and the audacity to hang up. My other accounts have gone into arrears because of the.
