Pathetic service

On the 31st January, I ordered a meal from the Nandos website for delivery. The eta for delivery was fifty minutes. After an hour of no news from the store, I called them to find out the eta. I was told it would arrive within the next few minutes as the driver was in the area. After 1 hour and 30 minutes, I called again and was told by the manager on duty that the driver was out on delivery, my food was still instore and she could not tell me how long it would be. The driver had "other" deliveries and would deliver my food when he got back to the store. After 2 hours I called the store again and cancelled my order. The manager on duty was not sympathetic at all and said she would cancel. It is 10 days later and I have still not received my refund. I have sent numerous emails and have also emailed Nandos Head Office. I have established that the area manager is a gentleman called Abdul. The staff refuse to give me his contact details and inturn he refuses to deal with clients. I have also established that he also Manages the Eldoraigne store where I had the same problem previously. The staff have indicated that they only have 1 driver who cannot handle all deliveries. Seems as though both these stores want the benefit of the deliveries but refuse to employ more staff to deliver. Pathetic service which keeps on repeating itself.
