Nandos ****ming

I placed an order yesterday for delivery at 19:31 (318/ST***9), with a delivery promise of 20:20 (the store I ordered from is 10 minutes or less from my place of residency). At 20:30 I attempted to contact the store and the number took me straight to customer care. I called at the very least 5 times, on a few instances the option 2 - delivery tracking it was not picked up and hung up, I used the order option and I was transferred to another line that immediately hung up. After these attempts I drove to the store while attempting to get answers from customer service. The last agent I spoke to intentionally **** saying that the driver was on their way arriving at my property soon, however they were unaware that I was at the store with my order in my hand at 20:50 and the delivery driver had only arrived at that time to collect my order. 30 minutes after I should have received my delivery. I would like to point out that Nandos adds a surge charge for delivery orders this is on top of the delivery fee. I was not refunded that money and I had to go collect my order myself so essentially I was charged for a delivery order but I had to collect it 30 minutes after promised delivery. No one has contacted me to rectify this issue, so essentially Nandos stole 45 rands from me
