Very bad service!

I bought goods at tfg, some items were delivered but one of items was not delivered. It's been four months and I still have to received my refund. I called and even sent numerous emails, also wrote to the ombudsman for assistance. My account is being billed with phone calls interests but they still have not refunded me. I want all the charges removed and my refund. This is the second review I'm writing and I still have not received any response from tfg.! They have 15 working days to respond to my query at the ombudsman and I want to know how their charges are going to be removed. Till to date I have not received my refund but they have the guts to charge me extra fees! I'm tired of tfg and I'm willing to take this query far to get assistance!
