conversations with b(l)ank people

Further on my sudden massive increase in available credit.
Decided to ring the bank today to see if the approval of a $20,000 credit limit was, in fact, real or, more likely, a typo.
Yes, two people were able to tell my that my credit limit had been increased to $20,000. No, it did not appear to be a typo, it was actually $20,000.
Hmmmmm.
Did you know this figure represents substantially more than half my current annual income?
Could I perhaps change it to something more like $2000 ie. what I had asked for the the beginning? Would be prepared to accept $5000 if pushed.
Only if you put on a red hat, spin around three times and jump through hoops.
Right.
Well, red hat, three spins and several hoops later it appears that my credit limit has indeed been reduced to $2000. A confirmation letter will follow. Who knows what it will contain – although a colleague has warned me that I might find the credit limit has been reduced to $200!
As a customer I’d have assumed the bank would have more control over its zeros.
