NO SERVICE AT VOLTANO ACCOUNTS

My unit was sold and registered in the new owner’s name on 3 March 2022 already. In the process my levy account was paid twice, once by deducting the amount when the final payout was done by the attorney and I also paid the account when the account was sent to me. I am sure this happens all the time when units are sold. This over payment should have been picked up by Voltano accounts without me intervening, BUT two months later and many emails later I have still not received my refund. Rina who is supposed to assist in this regard is still asking for proof of payment on every email that is sent to her. Proof has been sent 6 times already and she is still asking for it. I really am at the end of my ropes.
