The customer service is not able to give any info on this.
First of all it's hard to reach customer service because it takes a a lot of time and the ivr options are very difficult and tricky to navigate, after all the effort the customer service is not helpful.

If this is because of not maintaining account balance because i move my amount to different account as soon as i get salary. Then please note this is a salary account and deduction on salary account is not permitted.
