Extremely bad service. My oven is probably in a worse state now than before, after paying call out, fixing the problem and a service, a bill of 1950 ZAR, now I’m convinced there is a gas leek. I’ve requested for them to come back, twice they have just not pitched, not contacted me back after several attempts on my side. I paid immediately, trusting that they had done the work quoted and invoice promised, nothing received… now I need to get someone else… just madness that this can actually happen with no repercussions..
