Spectranet — paid for a new connection which I didn't get, they promised to refund but not paying back

Address:

Spectranet, 494 1st Floor, Chinmaya Mission Hospital Rd, HAL 2nd Stage, Indiranagar, Bengaluru, Karnataka 560008, 560008

I paid for a new connection with spectranet, its been over three weeks, now they have not given me the net connection nor paid back my money. They are sending copy paste message on facebook messenger to irritate me and are not refunding the money which they agreed upon. The sales guy who collected the document has been polite, while the other so called service engineer would call me a and not turn nor pick my call. Have pasted the copy of the receipt.

Kindly do the needful.

Regards,
Mahendran
