winner: good for you that you have got your card.
As for efficiency, well I must say OCBC pretty efficient except for sending out the card via normal post but this has more to do with cost i suppose. Why I say OCBC efficient:
1) zenquix got his card within a week - submit at application branch collect at branch.
2) I called them up middle of the night to ask about the card when it was first reported here last month. CS was unable to assist me on my queries and said someone will call me next morning at 10am. Well they did call me around 10.30am but my phone was set to reject UNKNOWN calls. Called them back during normal working hours and was told application takes 5 working days to process.
3) I faxed in application form on 18th Aug after 5pm. Card was sent out on 25th Aug (via normal post!). Five working days to approve application as informed.
4) Spoke to CS after 5pm yesterday as yet to receive card and asked them to sent to branch. The CS promised to call me back this morning to inform me how soon I can get the card. At about 11am my secretary informed me OCBC called the office and left message, so checked my phone and it recorded 6 unknown missed calls as my phone was set to reject unknown calls. This shows the CS commitment to contact me.
5) Return call to OCBC CS but the CS attending to my case was busy and gave them another mobile number to call me. But I also forgot to reset the other phone to receive unknown calls too

At 1.30pm after meeting saw missed calls again (this time 3 for each phone). Called OCBC and was lucky the CS entertaining me happened to picked up my call and he informed me that due to raya can't sent card to branch before Thursday and asked if it is ok to pick up at HQ. I said ok and he said will call me back. This time set both mobiles to receive unknown calls, hahaha. Within 10 minutes CS called me to inform card can be collected after 2.30pm on Thursday at HQ.
5) Many people here can check on the status of their application, processing department doing their job and info updated to system.
So from my experience, OCBC CS are committed just like HLB CS and AMEX CS and a particular CS at Alliance where they will call me up as promised to attend to my matters. I must also add that all the CS I spoke to were very courteous just like AMEX CS. Too bad comes 1st January the max rebate is only RM50.
From your words above, seems you are a very big customer.
I am just a small potato. Treatment is different.
