FRUSTRATED

I feel like there's a note left on my account or file or case with SARS. I spend hours to wait on the queue, and as soon as I get an agent then give my details, the call always cut. I submitted callback request and noone ever called back. All this because they owes me. After 21 days, they come with new request and delay my refund. When I manage to speak to someone, they tell me that everything is fine. This is very frustrating and unfair. I'm not the only one going through it. Where is the professionalism guys?
