Very Poor Service and Communication

After I bought a airfyer "Capacity: approximately 15l" I received my order a couple of days after payment. Once I received the box I realized its quite small. So I opened it and was veey disappointed in the size.

We were waiting for an extra large fryer because I heard people are complaining for the 4-6 liter machines as they are too small. So the 15L one sounded good.

After I inspected the machine I tried to communicate with One Deal A Day? I've send them a message on their.whatsapp nr in 21 Feb and they inly rep**** on the 23rd where they said they will check my mail. So my wife emailed them the following after several attempts via whatsapp, messenger and emails;

"RE: ORDER #543737 | Good evening, We have now sent numerous messages without reply. The item delivered is definitely not a 15 litre Air Fryer! It’s barely, maybe a 5 litre, this is false advertising as your advert said it’s a 15 litre!

Could you please let me know if you are going to refund us for this item, as I’m definitely not happy! Please advise on way forward"

We asked for a manager to get hold.of us with no reply or communication up to now 28 Feb. This company had zero communication skills and is definitely not helpful at all. I am very disappointed and would like to be refunded but there is just no way to get hold of a capable person to communicate with.
