Paytm — Money paid_ purchase of items barred by paytm

Address:	Ahmednagar, Maharashtra, 414001
Website:	paytm.com

I have selected few Items like AB exerciser from PAYTM before DIwali as their were Offers and I have Paid Money of Rs 4500/- to the PAYTM wallet. Later the delivery address cannot be saved and neither the Java button (in sky blue) ' Proceed to Pay Rs 4490/- ' when pressed would not take the web page to the next page for the process of Payment to be completed.
When the Problem was addressedto PAYTM customer care vide their email id [protected]@paytm.com the response each time was not consistent. I was asked to send so many details by several people on the other end and when I did suffice they asked more. All the communications are attached.
The payment f Rs 4500/- is with them and I cannot purchase anything and address needs to be typed everytime.
Is this whole business of www.paytm.com in india is a SCAM? like collecting money in the form of wallet and the shopping is it a complete fake ? is my doubt.
Once you read the contents in the attached .jpeg imges (from 001 to 07 in ascending order), your goodself shall arrive to the same conclusion as mine.
Kindly HELP people like me in India, to save us from such a Scam/ Fake/ fraudulent online shopping business before they Cheat more.
