Hollards unresponsive

I had a suspected leak at my property. The plumbers Hollards sent could not find anything and then proceeded to replace a 'pressure reduction valve'. This seems to have damaged the plumbing and/or geyser. Hollards refused to pay for anything and now I am sitting with a damaged sealing and who knows what else.<br> <br> And if you phone the 'emergency' number it takes two days for anyone to show up.<br> <br> I think the time has come for me, PPS short term insurance and Hollards to part.
