Late delivery/payment issues

I ordered a pizza online, which was very convenient at the time. One hour later my pizza was still not delivered. I phoned the Brackenfell branch (twice, I was cut off the first time when they put me through to the manager). After giving my phone nr, the person could see that my order wasn't delivered, and said that he would follow up. My pizza arrived shortly after that, but the driver wanted payment. I had to explain to him that I ordered & paid online. He wanted a receipt, and I had to explain again that since it was an online transaction, I don't have a hard copy receipt, and showed him the receipt which was emailed to me on my phone. About an hour later, I received a call from the Brackenfell branch asking about payment and a receipt. I had to explain again that I ordered & paid online, but that I will email the receipt to them if they give me an email address, which I did. This whole experience was very unpleasant. Aside from an apology, I didn't receive any compensation for the late delivery. There also seem to be issues with their online system. I certainly won't use that, or do business with the Brackenfell branch again any time soon.
