Canon India — Non delivery of canon pixma offer

I purchased canon printer under the offer, submitted all required documents and was informed I will receive the delivery in 45 days.. it is months now and I keep chasing them (complaint no 125784) and they don’t provide details. Every time I am told please send your address and I submitted address on the email, on sms but still same response every-time.
It is really sorry to see a company like canon deliver such a poor customer service. I would really like to get a clear answer whether I will receive it or not but don’t fool customers with offers that you cannot fulfil.
Looking forward to resolution of this issue on priority.
