Standard Chartered Bank — credit card limit reduced and blocked

Address:

Thane, Maharashtra, 421201

I hold credit card of standard chartered bank since long time.
Often i used to get information about pending payment very late i. E. Near to the due date and then late penalty is applied instantly.

About an year back i increased my limit on card to 1, 00, 000 and there was no problem and standard charter bank was happy about it.

But on feb of this year the limit was reduced to 10, 000 without my consent and explanation given was "we decided to reduce as per bank policy".
I hold only one credit card of this bank and god knows what is the basis for this policy. When i inquired more answer i got "we verified all your accounts across globe including all other banks??? I mean who gave you information about my all other bank accounts??

Furious over this i decided to close my card which had around 34, 000 redemption points and some 1500 cash back.
I order maximum items i could from redemption points and transferred cash to my card and paid the pending bill of that card.

Still there were 450 rupee to credit present. The customer care representative told me about how to redeem points but god know why she just blocked my card after amount was redeemed.

Now to get my 450/- back i have to get new card!!! Or else i just forget my money.

So as per bank policy they think i am poor enough to reduce limit from 1, 00, 000 to 10, 000 but rich enough to give them my hard earn money 450 just as charity!!!
