Debonairs Musgrave my family and I will never order from you again!

Last week I ordered a pizza for dinner at 18:05pm from Debonairs in Musgrave shopping centre. An hour later no pizza. I called the call centre at 19:10 querying how far is my order. I was told that the shop only has two delivery drivers. So I asked why are they accepting online orders for delivery if that's the case? I was told they will call the store and get back to me. 20mins after that I get a call saying they apologise and the pizza has left the store on on its way to me now(19:35pm). At 20:06 I call them again and they said they will ask the store manager what's going on. I then asked them to give me the delivery guy's direct number but they refused. They called the store then called me back after 10 mins saying they were not sure but its left the store. FINALLY my pizza is delivered to me at 21:40pm . Over 2 and a half hours and COLD!!! I called the call centre again telling them that I want a refund. There was no "HOT DOT" on the box. It was actually peeled off. There was clearly a spot on top of the box where one could see a sticker was peeled off! I told the call centre agent about this and I was told they no longer have the "Hot Dot" promise that's why it weren't there. The call centre agent then told me she will get the store manager to call me. It is now the 4th day and still no call from the manager. I had to microwave the pizza and the texture was like rubber and chewy. I threw it out! I will NEVER EVER order from that store again! I love pizza but Debonairs Musgrave....You suck!
