IFB Industries — Non-receipt of third free servicing of my 3 star 1.5 ton split AC

Address:

Bilaspur, Chhattisgarh, 495006

I have purchased a 1.5 ton 3star ifb split ac in march 2016. I was supposed to receive 3 free servicing. But till date i got only two free servicing. When i contacted for third free servicing through customer care of ifb i was informed from the service centre at bilaspur/chhattishgarh that no free servicing will be granted as one year time has elapsed. My question is that as per company assurance/policy i was supposed to get three free servicing. If they have not extended third free servicing within a year then where is my fault. Therefore as per company policy i should get third servicing without any cost.
