Disgusted with Nandos customer service

It's so disappointing to write a bad review about a place that you have been going to for years, I decided to use the online order for nandos today I filled in all required information and received a confirmation time for my delivery and the payment due in the website. 5 mins later I noticed I didn't receive any kind of SMS or anything to confirm the order so I called the Nando's in Phoenix to find out if they received the order they advised it will take 10 mins for it to reflect so I waited. Then itd 12:10 and I didn't receive my food so I call the store again and they tell me they never received the order so I have to wait another 45 mins for food so in total that's 2 hours I am waiting for a piece of chicken and a bowl of rice 2 hours that is by far the most ridiculous customer service I have ever received and it is not acceptable and I hey manager would not come to the phone to explain anything to me they instead told the cashier to take the call. I am disgusted with the fact that no one found out what the problem was and where it went wrong and then the lady that answered the phone at the store tells me " oh that's why it's better to pick the 3rd option to get it from the store" so u basically telling me that u guys have a online order system for nothing???
