Vijay Sales — a month delay in delivery of washing machine, yet to deliver and now saying to accept another model

Address:

Gondia, Maharashtra, 400097

I have booked the lg washing machine on 3rd july and delivery date mentioned was 10th july on the bill and sales person confirmed the delivery by that date. But now its been almost a month and i m yet to get the product. I have called vijay sales more than 10 times but they kept on saying it will come in 3-4 days but its yet to come. Now when i again called today customer care they r saying lg has stopped production of this model and u will get the new model and that too not sure when??
I find it complete nonsence and unprofessional as you people r still not sure as by when we will get the product and which one??
Need support and quick help
