unacceptable attitude to fix their mistake

i had placed an order on the app on the 20/10/2024 for 2 packs of diapers for my baby. delivery service was closed and i had to wait for it to be delivered on the 21/10/2024 at 9am. my baby had 4 diapers left, on the 21/10 the delivery was completed only to find that i was delivered 4 bottles of domestos and no diapers. i am away from home hence i used the 60 60 service and there is no other way for me to get diapers to my wife. i called the call centre and they directed me to the app to place the complaint. i was then told that it will take up to 48 hours to be refunded. i explained my situation to the consultant that responed to my complaint and they did not care that my child does not have any diapers left, i was then assured that the refund will be completed in 5 mins , over an hour passed and no refund, i called again and they said there is nothing that they can do. i find this totally unacceptable that this is a checkers problem and not mine , i have been inconvenienced in a major way and they have such a flippant attitude to their mistake. i understood the mistake but they are in no hurry to rectify it, i am left more frustrated than anything else and my baby still does not have any diapers.
