Puzzle of Insurance Policy

A few owners had gone to the management office to request for new insurance policy after the insurance had expired on 30 Apr 2012. However the staffs were  unable to produce any insurance policy document. On the same day 4th May 2012, this notice was put up on the notice boards. To our puzzle, questions mark comes up?

1. Why no mention of insurance company, if change of new insurance company?
2. Is there any RFI or Tender officially done? If yes, why no show on the notice board?
3.On our monthly bill already stated the amount to be paid for the insurance and the notice come up after that. The chronological order is wrong? Shouldn't the notice is up before the amount of insurance printed on the bill?
4. Are we paying excess amount since it is lowest quotation? Will we get refund?

Me ask sky??? No Answer...
