I don't even know what to do

Good day

The geyser was installed on Friday but it's not connected to the electricity as it was moved to a different location. The electrician came on Friday evening and said he will need to come back on Saturday as it might be quite some work. I never heard from them since, it's Wednesday today and I still cannot have hot water. May you please allocate to someone who can really assist me. I honestly don't know what to do anymore. I'm tired following up telephonically. I'm a failure to my family at this point. No hot water from 17 December.
