Redbus — refund not credited

Address:

600033

I had booked bus tickets (3 tickets) through red bus app from chennai to angamaly (& vice versa). However, we have cancelled the booking on 14th january'2019.

But the refund is not yet credited. There was no sufficient response when i had contacted the red-bus customer care through telephone.

The ticket nos are:
To angamaly - tn2g[protected] seat nos 15, 16 & 17
To chennai - tn2g[protected] seat nos 15, 16 & 17
