Never got the full amount of cushion s , contracted the supplier several times, but still was missing too

Love the colours on these cushions, they're very comfortable too.

My first parcel only contained 2 cushions when it should have had 4. I raised this with wayfair and was advised that the remaining 2 cushions would be despatched to my dismay a parcel arrived today with one cushion instead of 2. I now have 3 cushions instead of 4 what is going on? The cushions themselves look of good quality pity about the error in the service.
