Kindly help me
I have even complained in the bank and blocked my debit card.
I saw on the internet that other people are suffering from the same problem too.
Shall i go and complain in the consumer court myself?
Please look into it and tell me the way to resolve this problem.
26000/- is not a small amount for me.
It's very hard earned money and nobody us giving me the right response as if it doesn't matter.
