just called Citibank to change over to the Citibusiness Gold card and it was a pretty painless event.
The lady advised they would do a check and I will be notified by mail within 4 business day. Will get a new pin issued and then need to creat a new Online account as well.
All my current rewards points will be maintained and transferred to the new card.
SO called Citibank and spent an hour on the phone with them. She wanted to get this card, and also get rid of her other Citibank silver card (so, no real additional risk to Citibank)
1) Can't apply for this card because it is invite only. Told them that you could apply online
2) Was told then "just apply online". SO pointed out that this takes time, Citibank already has all her details. Please just reuse those
3) Was told that she had accepted a credit limit increase in November, so no additional applications could be made for 6 months. SO pointed out that she didn't want to get an additional card or increase her exposure - just wanted to replace one card with another
4) Was told she should close her silver card, and put in a new application for this card. SO replied that would leave her with no card.
5) This was passed between about 5 different people in the same call centre, who were going around looking things up and so on. I listened to part of the call, and it was very frustrating - I would have blown my lid - a lot of repeating things that would appear to be from a "script" that didn't really answer/address anything SO was saying...
Net result: no application. Was just easier to wait another couple of months and apply then.
