WORST SERVICE EVER

Today the 30/11/2018 at approximately 10:33 i placed an online order and requested the order be delivered at 12:30. I paid online via my credit card. The order was to be delivered via the Verulam branch. However I realized i made an error with the order 10:36 & and wanted to change it. I called the Verulam store, the lady that answered was so rude, she told me that she could not make the change and the order already sent out, she then cut the call. I tried the store several times after this and was constantly cut off I proceeded to call the customer service number and spoke with Regina. She advised that she would get the manager to contact. About 20 minutes later I got a call from a store manager from their Bethlehem branch . This irritated me further. I called the customer services again and stop with Ashley who advised once more that the branch manager would call. at about 12:15, I received a call, it was not the manager, the lady on the other end of the call asked me "what my problem was" I told her that since I am vegetarian i needed to change my order. They told me that for the item I want change to they did not have pesto. I asked what was my other options were.... she said I will call you back. at 12:30 which was my lunch break i called the store again to find out what was happening. Seriously i didn't thinking changing an order that i had already paid for would be such a hassle As this was becoming increasing frustrating as she kept cutting my call, I finally decided to cancel my order all together since my lunch break is only 30 minutes long. I called the customer service for the 3rd time to report the attitude of the staff member at the store. I was told by Ashley that he would lodge a formal complaint on my behalf and I would receive my refund in 2 workings days. He advised that I would not receive reference for my call but an sms. After this i received a call from the store manager (finally) i told him that was willing to change my order but since my lunch break was alost over and due to the bad service i had received from the lady earlier it would best to cancel the order and process a refund. He proceeded to say "well goodbye" and cut the call. Is this the way manager talks and treats customers. All this because I didn't want a meat pizza. Several hours have passed and I have not received an sms from customer service. I would like a full refund for my order. Its sad that the attitude of one staff member and one manager has *****ed my view of Debonairs Pizza. I will ensure that I no longer frequent any of their branches and will encourage my friends and family to do the same. I hope that a someone form Debonairs customer service read this review and is able to assist me in respect of refund. I shouldn't have to pay for an order I never received especially when the service was beyond disgusting.
