Paytm

Dear sir,
I ordered a dell laptop on 19th mar18 order no. [protected], and i received the laptop on 24th mar, 18.
Sir, but when i received my laptop, i got only laptop's invoice copy without extended one warranty policy.
When i booked my laptop through paytm, i selected the check box for extended warranty.
I have try to connect you at your customer care ([protected]) so many times, but it always came engaged/busy.
