IDBI Debit card
Card not working

I have a debit card from IDBI. From past 2 days I not able to use it to shop for anything. Everytime I use it, the machine gives the following error "Do Not Honour". Even though I have enough balance, I am not able to use it and I look like a thief in front of the shop owner. It takes about 30 mins to connect to their customer care and after connecting to them the person says that they have a technical problem. When I ask them to explain, they say, they cannot help.

Please do not open any account with IDBI. Thats my sincere suggestion.
