Address:

122004

I have citibank credit card with no "*-*-*-7450, after the use of 8 months bank has block my credit card without informing. When i called & ask no body is giving proper reply & each & every time complaint reference number is given. Which are:-

4160
3686
8148
1381

Again they closed it without updating, after so many calls & followup i asked to reedem my rewards points for this they have to issue voucher agianst the amount. But from january 2018 till now i waiting for their voucher & the same is not received yet.

This is how citibank value their customer!!

Bsides of writing complaints to thier website, they have not called & resolved.
