Manhattan Credit Card — New card with the same number sent

Hi,
I am using the manhattan card since a few years now.
This Jan I had a discrepency with the statement and so was advised by the customer relationship manager, that it would be advisable to block the card as it might have fallen in wrong hands and no further misuse could happen.This being a sensible suggestion I agreed and got my card blocked.I was told that I would receive a replaced card soon.I got the same too.When I used this card for the first time, it gave some error, the person at the counter told me there was some problem.Ithought maybe the card had not been activated. When I contacted the helpdesk again and told them the same they said that the card was already activated and that I could go ahead and use it.
I had been a regular card user but these experiences left a bitter taste and I nearly stopped using the card.Today, I had gone shopping again and thought let me try the card again and to my shock and horror the person at the counter gave me a dirty look and showed me that the ADC Machine showed "PICK-UP". I asked him to explain what that meant and he said that go ask your card company and I am not returning the card to you. This was proving to be very embarrasing with everyone looking at me and I did not understand what was happening.I called the bank and they told me that this card with this number has been blocked and that my new card had another number.I told them I had both cards in front of me and they had the same 16 digit number.As I could not speak to the helpline and the Standard Chartered person who answered for the card refused to help me, I later tried the Manhattan Helpline again.This time I got through and spoke to the representative. I explained the whole issue to her telling her about all the embarrasement that the whole episode had caused me.I also had another reason of concern which I explained to her.I told her that I had to register for an exam which would be further delayed if I do not get a card soon which would be a loss for me not only in terms of money but also in terms of the hours and days that I was losing in preparing for the exam. Since I had to pay online the card was the only way that I could do it and that to send me that card at the earliest considering that all along the mistake was theirs.She spoke to her senior and said that nothing could be done and the normal practise of 7 days would be followed.I was quite worked up by this whole issue and found them very insensitive to the whole predicament that I was in .I told them that if they could not help me and as I was facing a loss as I would not even receive my study material till I made the payment meaning I cannot start preparing for my exam, I would then take some action against them.She told me that I could go ahead and do so.This is why I am registering this complaint, else probably I would have settled it if they would have replaced my card at the earliest.Now I want them to face the consequence of repeated embarrasement caused and the delay in my registeration and preparation for my exam.
