SARS RETURNS

I went to the SARS branch in Umhlanga KZN to do my returns on the 21st of July.I submitted every document that was required because I am a person who is living with a physical disability so I also need to submit a ITRDD form.As I was doing my return with an agent,I informed the agent that I am no longer using my previous account as I have a personal loan there so Im repaying that loan with an arrangement.Then,I asked the agent to please update my banking details and I believed she did because she even confirmed the last four digits of my account number as it appears on the system.To my surprise on the 30th of July they paid my refund to the previous account,I also recieved an SMS from SARS informing me that if there is any enquiry regarding the refund,I must go to the previous bank for them to reverse my money of which is highly impossible however I did go to the previous bank sk the consultant told me that unfortunately they can not help me because I did not deposit the funds so SARS needed to do a recall refund.I went back to SARS,luckily the same agent who assisted me on the 21st of July was the one who assisted me on the 30th of July as I was back to do the recall refund as insturcted.Fortunate enough the agent recalled my face and remembered everything we discussed.She even confirmed that she did file my current banking details but she will do the recall refund and I will recieve feedback after 21 working days of which is today and there is no communication.I called yesterday to enquire and they responded saying they are not picking up anything on the system.I can not always go to the branch because it is very far.I need to pay for tolls and petrol and I do not have that money.SARS is very irresponsible,they wanted me to go to the bank and rectify their mistake.Its their fault they must fix it
