Paytm — Product not received but paytm says product is delivered

I've purchased aveeno baby wash and shampoo from paytm on 7th june 2016. I've received a mail on 9th june stating product has been shipped.In less than 2days i received another mail that the product is delivered... But it never reached me... I tried mailing to paytm and raised many complaints... But they never took care of it. The only say that they require 3days to work on it on priority basis... It was already 13days passed.. But there is no response from them... Complaints were been raised in the grievence on level by level to all the levels... But no use... I think they is scam happening in paytm... That is the reason why paytm is not having customer care support over phone... They only display phone numbers but no option to speak to customer care executive
