Who called from 20599000

No comment

I called back this number and they said they are from HSBC. Dunno whether true or not

Same thing. Called them back. HSBC. Lady on phone said most probably their sales rep called initially.

Yes, from HSBC centre - sales representative promoting personal loans etc.
Can't speak proper english for nuts, and obviously reading from a prepared script.
Shame on you HSBC

I was at a client meeting when this person called. So i hung up. Then I received 4 more calls from this number within the next half an hour. Is that how you call your customers these days, HSBC?
