very terrible experience shopping at TFG

I bought items online and paid full amount via EFT I then returned one item online before they could dispatch my order it was on the 15th of December 2020. I was promised my refund was going to take place within 7 working days. I didn't get my refund with that specified period I then called TFG customer service and they transferred my call to online shopping support where I spoke to Madeline. she assisted me and told me that she would escalate the matter to their people who control banking refunds and promised that I would get my refund within 3 to 10 working days. I still haven't received my refund even today and now it's more than a month and no one has that kind of patience. they are very terrible because I paid with my debit card what is so hard to refund it the very same way I paid.
