Pathetic staff and service at courier guy

Parties involved : charmaine dafel and someone named 'chantel' at the jhb offices. An acc closure and refund request was forwarded with all relevant info on 7 Dec. I had to ask for turnaround time (7-10 working days). It was not provided. I had to follow up in terms of progress. I was not mailed or telephoned at any point. This was absolute bull**** and pathetic so I phoned on the 20th Dec to find out what the hell was going on. A very brusque/terse/unpleasant female named 'chantel' (not 100% positive) said they had moved offices and these requests would be delayed. NOT MY PROBLEM . She fobbed me off by saying charmaine would phone me later. It's now 23 Dec, NO calls. NO RESPONSE TO ANY EMAILS WHATSOEVER. NO RESPONSE ON SOCIAL MEDIA. Joke of a company. Zero client service ethic. In fact, I've had better service from local government offices. That's saying a lot. I want this resolved and I want the acc closure/refund. Companies like this a still in business and I cannot fathom why.
