I've found now that they have assigned me a restricted CoS whereas as I am already working under Tier 2 (General) in UK and am applying for a change of employment (to work for a new sponsor), I need an unrestricted CoS.
I had booked a premium service appointment earlier today for next Wed. but may now need to reschedule that.

What is the procedure for getting this issue resolved ? Does the sponsor have to cancel this CoS & make a new CoS request for an unrestricted CoS ? If so, how long does that normally take ? I've read online that getting an unrestricted CoS is quicker as there is no annual limit on it and a sponsor can generate and assign it within a few hours from their SMS account (if they have a spare allocation left) without needing UKBA's approval beforehand. Is that true ?
Can't they just contact the UKBA and explain the issue and maybe rectify this by adding a sponsor note to the CoS ? My start date for the new job is in 10 days and now it seems like I won't make it.

Please help me out.
P.S: What happens if I apply using a restricted CoS ? Will my application be refused ?
Also, if I reschedule or cancel my premium service appointment, will also I lose the entire £1,001 visa fee ?
