Theft of Refund

This is the most appalling institution i have ever had to deal with. Two instances, 1st instance : I payed my card of last year 2017 and called these people to reduce my credit limit and my instruction was never adhered to, things happened in life and I ended up using the credit again. 2nd instance: I have now paid my card off again!!!! and have requested cancellation/closure of my account - I get a call from their agents trying to persuade me to keep the damn product and I instruct them to close my account because i don't want this **** card anymore and these neanderthals now send me a statement reflecting that I am in credit!!!. I don't want the product and I have paid you off in full. must we put you guys on Radio 702? or how about speak out on TV???????? should I rather now resort to serious brand damage for me to get my instruction fulfilled and my money paid back? you are quick to handover accounts when one owes yet not quick enough to act responsibly as an organization and give back what is due to me? absolutely disgusting *****ic behaviour as well. clearly this is the organizations ethos, lets not only rip them off with our crazy and ridiculous prices but lets also ***** the last bit they have when they leave.
