VERY BAD SERVICE!!!

I placed and paid for an order of over R2000 on 09/5/2020. I booked a delivery slot for Tuesday 12/05/2020. The order was not delivered. Then I got a call from Jason at Fleisherei that my order was processed and would be delivered on the Wednesday 13/05/2020. Still no delivery. Then later the same day I got another call from Jason saying that I fall outside of their delivery zone. He could send the order to the closest branch and I could collect. If I could go shopping I would not have ordered online. We are pensioners with no car!! He then put all the blame for non delivery on me saying I entered the incorrect code for delivery!!! Oaktree's postal code is 1739 which falls under Krugersdorp which is 1739 so how do I fall outside of the delivery zone. ALL other couriers deliver here no problem. He then said he would do an immediate refund. That was on the 13/04/2020. To date I have no immediate refund. It is weekend so I have to wait another 2 days for nothing to happen!! And in the meantime we have no money to buy other meat!!! When I contacted Jason to find out what is going on he keeps saying he will find out from the finance department. When I contacted Jason on 15/05/2020 to find out what is going on he said he would check and get back to me. He NEVER got back and today when I phoned no one could assist me. This is totally unacceptable. They have had my money for 8 days!!! I am pensioner with no transport still have nothing!! This is a disgusting way to treat customers!!!!
