Alright folks, was going through the last few pages and found some common queries regarding variant change and holding 3 variants of Sapphiro CC. Summarizing it for all:
If you hold VISA variant of any ICICI Gemstone Card (RubyX, Sapphiro, Emeralde), then you can opt for variant change to Dual variant (MC+Amex). And vice versa, from Dual to VISA.
ICICI Bank, on conversion of VISA to Dual, or vice versa, DOES NOT close the old variant. So, you can keep all 3 variants with you.
How to do?
Request ICICI Customer support on Twitter. They will call you. In the call, they will tell you that your old variant will be closed. Don't worry, Just confirm it, and see the magic. Within a few days, new variant card will be generated and sent to you. All 3 variants will be active. You will also get another Dreamfolks card.
(Sometimes customer support may deny conversion, just request again. Its just that customer support agent is non-co-operative.)
Now, summarizing the bad news from this thread: oFr some users, ICICI have closed old variant cards after new variant card delivery. But before closure, they always call you to tell you about your new card benefits. So, post card delivery, do not accept any calls from ICICI Bank for some weeks. There is at least one incident where even without picking up this call, the old card got disabled. I would say that is pure bad luck. Rest up to you. Anyways this variant change is NOT a one-time thing, you can request conversion anytime again.
For me all 3 variants active as of now (3 weeks passed post delivery of card). I still get calls from ICICI bank occasionally (once in 3-4 days), I pickup and then don't respond anything, until they cut the call.
