How we got Kelvin Ng Mee Chee's contact and quotation

Brief summary of how we got Kelvin's contact and quotation:

1.) Oct/Nov'08 - We got Kelvin Ng's mobile number from GPlan, when we first called GPlan office last year.

2.) 20Nov'08 - After meeting up with Kelvin, he submitted his first quotation under GPlan. (We still keep this quotation)

3.) Nov'08 - A few days after Kelvin submitted his first quotation under GPlan, he mentioned that he was leaving GPlan. He requoted us on his own.

4.) 17Jan'09 - We signed with Kelvin under his new company Artistic Design.

5.) Mar'09 - During casual conversation with Kelvin Ng, he mentioned that he was still with GPlan.

If what Kelvin Ng told me on Mar'09 was correct, I wonder how Kelvin Ng could quote and sign customer under Artistic Design, when he was still with GPlan? Maybe someone could enlighten me?

To be honest, it was quite difficult for us to believe that Kelvin Ng, who was one of the more talkabout IDs in a well known renovation forum in Singapore, actually did this to us. But if we look at Citigroup's share price today and compare it with share price 2 years ago, then unfortunately we have to admit that, anything can happen.

Anyway, up to now we are still yet to receive our refund from Kelvin Ng, 25 days after he terminated the contract on 07Apr'09.
