Vicky read your contract again carefully, there is alway a
promise there to state how many bid they can try ! usually it is 3
to 4 bid ! once over that amount of try, the contract is void as
they fail to secure the COE for you within the agreed number of
tries ,thus you are not bound by it anymore. That is to protect and
prevent the SE from hold you back after a number of tries.
As for deposit, you are entitled to get it back as the SE is the
one who fail in the getting the COE in the agreed number of tries.
Read your contract again !
