Pillar To Post - Call Centre Agents do not know how to help.

I am an expat working outside of South-Africa, hence telephonic communication is not always available. However, I make use of the Absa cellphone app to do banking. Long story short, SARS made a payment to my Absa cheque account, which now I have had to find out has been frozen. I cannot access the funds and I need it urgently. I have made numerous phone calls (even ended up in Vehicle and Assets Finance) which has nothing to do with my query. It is costing me a lot of money to keep phoning the call centre, and I even tried phoning my branch which is Vanderbijlpark, just to be put back through to a call centre. So far R600.00 in phone calls, I have no sent proof of funds and the standard bank account I would like the funds to be refunded to, to the Off Balance Sheet Loans department, and STILL NO FEEDBACK. I will appreciate a response on this please.
