Bad Service Complaint

I have bought a low cost fridge at Appliance King Pvt Ltd yesterday and I made a payment and as per our agreement they said they will deliver the product yesterday of which they never did and today I had to contact them again and they said the driver will leave their premises at 12:00pm when I called them back again they now saying the driver is busy testing the other client’s product to check if its working or not, I called them back again and they now keep on hanging up on me and their phone its now on voicemail.
