I am using mobikwik wallet from long time now and things I have observed about this wallet is:
Pros:
Good cashbacks
Have tie up with so many websites
Cons:
Pathetic customer service- If you get into some dispute of payment, forget that it will be solved before month
No customer care phone number
Dont use icici netbanking option on this website, for me twice transaction was failed and money was taken from my account. Had to struggle alot to get it back.
