1 Pizza delivered instead of 2!

What an horrific experience yesterday from Debonairs Northcliff! We did not have electricity at home last night and my first thought is what do we get for supper? So I decided to order online from Debonairs Northlcliff, what a big mistake this was. Ordering online was a breeze, if only getting my pizza was just as easy. So the driver pitches up with 1 pizza box and I query it with him, he still insists that I ordered 1 pizza with half and half flavours, wrong! I ordered 2 pizzas with each having half toppings on both as an extra (various options are available online) How on earth are there no quality checks at this store? Doesn't the supervisor or manager verify the goods being sent out before they leave the store for delivery? Furthermore, How on earth does the driver not verify the receipt to maker sure he is delivering the right pizza/s? My word, it seems like none of them know how to read a receipt as he was arguing that my half toppings indicated was actually a half and half pizza, shocking service, sies! He managed to call up the manager and all she tells him is, oops ja it was a mistake, they did not offer to make the other pizza nor did she ask to speak to me and apologise. What absolutely disgusting and pathetic service! I only end up paying for the one pizza and my poor mum is left without supper. We had specifically ordered 2 pizzas so we would each have our own. Never again will I order from Debonair's after this ********** experience. This branch is the worst ever, if you make/deliver pizzas day in and out and is your daily job, how do you get it wrong? Please can someone explain, what is worse is nobody takes any responsibility for this negligence. This experience has surely left a bad taste in my mouth.
