Has any one applied for this basis a FD? What is the minimum FD amount required for getting the Signature version?

When I went to the bank to inquire about the process to get the card via FD, the guy there told me its very easy. No documents required. Just credit the amount in the account, fill up the form and I will get the card within 10 days. If also informed that if FD <50K than credit limit will be 70%. If FD >50K than credit limit will be 80% of FD amount. So today I went to him again and said that i have transferred 100K that can be used for FD and requested him to process the application for Credit Card. I specifically told him that I need the Signature version and not the Platinum version. And this is where the fun begins. He comes back after 5 mins and tells me that if I want the Signature version, the minimum FD amount needs to be 188K (weird number). For the Platinum version the minimum FD amount can be 56K (again weird number). So I asked him why did he inform me about the credit limit of <50K and >50K FD amount the other day? His answer - I didnot confirm the minimum FD amount. I just told about the credit limit.

I am not very much interested in depositing about 200K in FD just to get this card. Any suggestions?
