Marg Compusoft — bad service from the company and no response from customer care

I had purchased a point of sale software from marg through mr x in dehradun.
The request was made in july 2016. Advance paid was rs 8000. After repeated followups mr x delivered some product in crude form without any billing / barcodes formats. He said the balance formats would be given in few days so that the software can be worked upon.
The product is not in usable condition and has not been used till date.
Most of the time mr x does not pick phone. If i am lucky and he picks the phone then he says he will come tomorrow, which never comes.
The customer care takes long to respond to the mails. They say you will get a call which i don't get.
Finally almost after 10 months i got a call from customer care. They have talked to mr x (Local partner of marg). He will come.
Mr x comes, says he has committed mistake. So you just pay the next year years renewal fees and i will give you the balance formats. We both agree and he says he will come in two days. Which he never does.

I am now done with marg services and want refund of my advance.
