Hello every one, hope your all well

I need help badly i have a 1999 2.5 v6 facelift and she has been in vauxhall for a few days for an mot, service and cambelt change day 1 mot failed on a tyre so was replaced and then passed the mot day 2 cambelt vauxhall then realsied they didnt have the correct cambelt to do the job, then yesterday they phone me and tell me that the tried to do the service but the "cam gasket is flooding out oil" and that they couldnt change the spark plugs for fear of oil flooding "in the head"?? i hope i have explained this rite so far

so really im after your advice all work has stoped on the car so the cambelt wasnt done as they said its not worth the money im putting into it, can any body make sence of what i've said? or have a made a complete lemon of myself?? more importantly do you think it can be fixed???
