Momemtum & 24Fix

On new years day at around 3AM my geyser burst. Luckily this was outside so we just closed the main and struggled through the weekend. I logged my claim with Momentum on the 3rd of January (CP328207.) They then appointed a company called 24Fix to come out to site and carry out the replacement of the geyser. This only took place, 8 days later on the 11th of January. The next day, all the pipes across the entire house started making a terrible sound every time we opened the taps, this was both hot and cold water. We tried calling 24Fix and after holding on for more than 15 minutes on each call, it kept dropping. Today is the 23rd of January and this issue has still not been resolved. Momentum have tried calling, we have tried calling and still no feedback or success. It's either 24Fix are a clown of a company or they have individuals that work for them that are ***********, you pick! To Momentum, this company is dragging your name is disrepute and I would suggest finding another contractor.
