Sony India — Tv has still not been delivered and service centre is just useless

I had a Sony tv which had problem with its screen, as the company stopped producing the part required for the repair of my tv . They had instead given me an offer where i could buy a new set n they would give me a discount for the old one.Till that point all went well .
on 18th june i had made the payment for the new tv, and was told it will take maximum 15 days to deliver . On 2 nd of july i had called the service centre, initially they were just ignoring the call, after repeated calling they informed me the item will be delivered by next week around Wednesday,
After repeated calls on the 7th of july, they told me the set has not yet come will reach them on friday, n it will be delivered to me on 10th of july . Guess what it is the 10 th of july n its still not here . after calling them about a hundred times they finally decide to pick up n tell me that the tv is yet to come n might come at night, so they will deliver it on tuesday .
now if they are getting the tv on saturday, why can't they send it to me on monday, why just waste another day . both the toll free number n the service centre are useless, they will just tell you we ll put your request on priority and get back to you in 24 hours . it has never happened . they will never come up with a solution and will just force you to do what ever suits them the best . would never recommend anyone buying from them . its already been 23 days, still not received my order . it would be great if they company was a bit bothered about their reputation n hire good employees n throw the one that are currently working in the service centre.
