Maiyas — two time they collected the amount

Address:

Bangalore, Karnataka

Here in airport on 2nd of may arount 6.52m.. We bought karabath kesaribath. One plate, one plate besebelebath and one plate idly sambar. And one coffee, and the amount came up to 452rs..
And my husband paid it through card and they said not credited and they collected cash also and said it will get reverted but still it is not reverted back... And the amount which ve paid through cash i have lost it since we were in hurry to get inside for security check..
So pls help me in getting back my 452rs..
