Hello Darren,
What is important is that the garage removes whatever sealing compound it added (the glittery particles you saw in the expansion tank). This will be time consuming, difficult and judging by other members' experiences, will involve multiple coolant changes using a flushing compound. It makes no difference whether the system is refilled using the manual method or vacuum equipment; both are approved in RAVE. You will also need a replacement thermostat because it is not closing properly.
If the garage continues to deny the evidence (the "glittery bits" which you say were not present before its involvement) then I would take your car somewhere else or do it yourself!
At least that way you can be sure.
Simon
