Standard Chartered Bank — standard chartered 360 rewards

360 rewards page is not working from past 3 days and they are not displaying any message on the portal until we go and redeem any voucher. One of the executive responded to my call, Vandana answered very impolitely and saying you can redeem anywhere and anytime but that is not working from past 3 days. I have enough of credit card points but unable to use them . After my call they started displaying message on the site opening page itself. It would have been done 3 days back itself and it wont get impacted me . Customer care people also cant take request on my behalf of on redeeming points. Very disguisting. Am a loyal customer from 8 years to standard chartered and the answers from executive is very disappointed.
Someone should train them properly.
