Ask the tech which part of the air seal they were checking.
There are typically 3 components:
piston to cylinder
cylinder to cylinder head
nozzle to cylinder head
And the less common is the hop-up to the nozzle.
Generally to upgrade your gun is relatively inexpensive. Parts range anywhere from 30-40 in total. That said, tech service + parts should not run you more than $80. If you paid more than this for such bad service I would ask them to redo the maintenance. A quick spring change should have only costed you $50 tops with spring and technician fees. You paid for more so you have a right to complain about their services.
