Shockingly bad service 3 weeks after geyser burst

Almost three weeks ago our geyser burst, resulting in us having to have the geyser replaced and the ceiling boards replaced because of water damage. Plumbers arrived the next day and replaced the geyser, but we have since had problems with a severe airlock and despite numerous phone calls to the plumbers and ABSA Insure by us, they have not returned to fix the problem. I regret paying them the excess monies, before a satisfactory job was done. After many phone calls and an e mail, a contractor came last week to view the ceiling damage but to date no one has come to fix it. This has cost us many phone calls and inconvenience with no end in sight. I have heard of the quick and efficient service received by other people I know using other insurance companies, for the exact same problem and I'm disappointed with ABSA who are currently advertising themselves with a superior all round servive!
