Tata Cliq — non delivery of the product

Address:

560066

Hello team,
I have ordered a refrigerator, later the product is shipped and processed and when it's out for delivery, they are telling product price less because of technical issue we cannot deliver the product

Now they increased the price of the product and telling me that product price is increased and they said if you want place a new order, they did the same thing twice.
They are arguing as the price was less due to technical issue for that price the product cannot be delivered so we are refusing the delivery, this is purely cheating if it's a technical issue they should have cancelled the order before proceeding, why they should keep it till the delivery time.. I'm very disappointed on this, i need the product now please let me knowwill i be able to get any help on this please.

Thanks,
Nanda
