Good not received OneDealADay not interested - blame the courier company

Been waiting nearly 3 weeks for my goods. Eventually looked at the parcel tracker and it has been in a 'We have experienced a problem with your parcel which is currently under query at our depot.' state for 9 days. No feedback from ODAD. When I managed to get a response via their archaic WhatsApp service they told me that they outsource delivery to Fastway Couriers and it is not their problem. I explained that I paid ODAD and that my relationship is with them - not a third party supplier, however they are not concerned.
