Refund-Banking details update

I submitted my tax return last on July and I tried to update my banking details on the Tax return but it did not want to update. I then contacted SARS to find out whet was needed and took all the documents needed into the SARS branch this was on the 17th of July. The consultant gave me the letter confirming banking details are updated and it will take up to 7 working days for payment to be made., 7 working days pass and no payment, the type of person that I am I like to follow up on things as people always drop the ball and I like getting kept in the loop so I followed up and I am now told I am told it will take 21 working days to verify with the bank. I am thinking to myself this doesn't make sense but I will give SARS the benefit of the doubt and I continue to follow up leading to 21 working days and I am told not worry it will be made but it will take an additional 7 working days for payment to be made. This is when I knew something doesn't add up because its a different story now and this is all after numerous calls and receiving numerous reference numbers and consultants telling you to hold on and then you hold for 10 minutes without them saying anything how unprofessional it happened twice to me luckily the call is free but really ********* a person like that should get a warning because you don't do that to a client where is the customer service s****s, but it has been my experience on 2 separate calls on different occasions but it should be dealt with because it is unacceptable they are on the other side of the line and can treat people the way they feel its totally immoral. I called SARS again and again to follow and they tell me the call is escalated to sort out my refund to be paid the escalation was made last week and I was told SARS would call me with in 24 hours and guess what that didn't happen. I follow up after that and I am frustrated because I am getting messed around and guess what the consultant tells me SARS would never call you, you would need to follow up with SARS so this is beginning to sound like a circus I was really annoyed and I kept my cool and brought my point across and she says to me please follow up next week Wednesday and this call was made last week Wednesday and guess what I call and I call and I am told there is no turn around time for the escalations department. I call the SARS complaints and enter my reference number and it says your case is still within the SARS SLA but no indication of what the SLA is. I call the SARS call centre again and I tell them I cannot get through to the complaints department and they tell me lodge it via Efiling they will respond. I then do that Wednesday night up until now there has been no acknowledgement from a consultant from the complaints department, how unprofessional can SARS be this to me is ********* they take your money when you pay tax but when you are owed your due they cannot pay satisfy the service and the money you are owed. I did my part I respected your turn around times from 21 days to an additional 7 working days. I have waited log enough I took my banking details that was requested my part was fulfilled. I don't understand why cant my baking details be verified you have my bank letter. Call the bank what is so difficult to do that because SARS is pathetic, rotate the staff put staff who are worthy and capable of servicing the needs of the people of the country who would go the extra mile because customer satisfaction is valuable.
