Bad service

Hello Peter .I have a complain about Debonairs. Last week Sartuday I asked my sister to order Pizza then she left after more than an hour and I already forgot about the Pizza a delivery cam to delivery and asked him if he has 200 change and he said yes and he gave the change then he left. After he left something click on my mind about the incedent were by I ordered Pizza from Westage and it came very late and I send the driver back so my colleagues explain to me Debonairs policy when Pizza is late and this time the sticker on Pizza package was black and I since I wasn't sure I whatsapp my colleague just aske again in what situations I don't pay for Pizza and she said the box has a black sticker and to my shock that I paid for the Pizza and delidery guy didn't even say that I don't have to pay. I phone the shop to verify the mistake but they didn't pick instead the phone was cut off. then I phone the complain line the gentlemen who was listening to my complain said the driver should have called the manager and confirm that Pizza was late so I dont' have to pay for and he promised to forward the complain and they will attend to my matter and he said he will call the himself and get back to me. after few minutes the call centre guy phone and he said he called but same thing happened to me no one picked up and he further said he write the complain and send me the reference number and further say the shop will call me back and they never did. I called the call centre again Yesterday and the lady said their system show sthat the shop is still going to call me but until today they didn't call and now I'm just wondering how many did they take advantage of me not knowing the black sticker and I'm ****ed off because of thier bad service at Watergate mall, this incident shows that they don't have customer service or their system doens't work properly to see how many black sticker were send out but paid. I'm not sure whether thier delivery guys knows their policy or he took advantage of me even with other incident at Westage mall the driver left with the Pizza and the only got from them is we sorry so in this case I'm not going to let go I want my money back and if I was in surbub areas I bet the service was going to be differ.
