SARS REFUND

I previously had a cheque account with Absa which was closed years ago, My sars returns were paid into that Absa account and I was advised by the absa collections team that I should send a statement of the bank I currently used so they can pay my refunds back till today I have been awaiting for my refund I put in the request on the 7th of July and till today I am not assisted, I was advised that they were awaiting for verification from Sar's but when I contacted Sar's they advised I can send my refunds statement which Absa can use. I got no update on my case no assistance at all and every time I call in they all advising that they escalating and they also can not provide any timeframe
