One Deal A Day not delivering

I placed an order in July 2023 and am still waiting for the order. When I give them the waybill no via whatsapp, it is the only way to contact them. I've tried online and it gives the whatsapp no. I get 8 electronically generated messages stating that delivery takes 7 - 10 working days and if I query something then they will take the date of my last query. I am not happy with the service that I am getting. I contacted their courier service who has stated that this delivery hasn't left One Deal A Day's warehouse yet, but I have a waybill no. When I go to the website it states scanning pending. I've used them before yet with this parcel I can get no assistance. Not a happy customer at all.
