Disgusting service @ Game store online

Hi

2 weeks ago I purchased my son's stationery online @ Game. Where they stated items will be delivered within 5-7 business days. First i receive a email stating the items were delivered which is not true. So i phoned customer care on the 6th January 2022 and the gentleman i spoke to says its a error on their side the emails were sent incorrectly and alot of people are phoning in regarding this but my package where handed over to the courier @ 10pm the previous night will be delivered to me on Friday 7th January 2022 because that is the last due date. Guess what nothing were delivered I phoned again yesterday 13th January 2022 and the lady i spoke to really tried her best to assist me. She said the previous gentleman gave me the incorrect information and my package were never handed over to the courier it is still at the store. She tried phoning the store no answer.and then she escalade the issue. I phoned again today and now has an answer for me. This lady also tried her best to assist me and promised by COB i will an answer. Its almost 3 no feedback. I also requested from this lady to cancel my order and credit my money. I do not care if the package is at the store or courier. I want this cancelled immediately. I am very disappointed and will never ever order online from you again. You have put me in a very difficult situation because school is starting on Wednesday and my son have no stationery. And now I have to make a other plan. CANCEL MY ORDER IMMEDIATELY
