Google India / Tez — money got stuck.

Address:

Thane, Maharashtra, 400605

I transferred rs 351 to my friend. The amount got debited but not credited to my friend's account. It's been 4 days since then. I contacted the support team, they said the issue will be resolved within 3 days of transaction. One of my friend suffering from same issue as his money is stuck since 20 days, can't wait for that long though. Please help me out.
