One97 Communications — paytm cheating people

I have registered paytm merchant wit 13 digit bank account number by mistake which is invalid, but paytm saying its valid. It should be 14 digit. They are not refunding the amount after regular follow up also. I am serious issue. I have been in regular follow up. Initially they told to wait & some executive told its will be reverted back. But now they are saying its transferred. How its possible with invalid account number if i ask. They are just telling its transferred. Its not possible means also they are not agreeing.
