Wireman not replying calls and messages after recent mco.

Wonder if it is a wise decision to change another guy to finish up the renovation?
All the hacking done and wires already in place and plastered.
Remaining scope: install lights, change old switch sockets to new, testing and commissioning new wiring works, basically finishing works.

I thought so too, new guy maybe need to spend more time organising wires. The only worry is if he suddenly turns up asking for money. 90% done but payment only up to 70%.
