absa insurance cannot deliver on there promise

I had a pipe leak 7 days ago, water all over told by the absa client service to switch off all pipes and a plumber will be in attendance within 24hr. Automated reply system worked well but 7 days later no water and ongoing leak. ABSA plumbers informed me they do not deal with any pipes other then polycopper, galvanised and copper. I have a multilayer piping installed, sabs approved and plumbing compliance certificate form Jo'burg municipality and was told by ABSA they do not cover it???? This is despite having fixed a leaking geyser two years ago with the exact piping. The PROBLEM ABSA contracted plumbers not fully qualified or equipped to deal with all eventualities and will therefore not do the work. Instead told to go to a private plumber and have it fixed and to invoice ABSA. Absurd that is why I am insured and why I should NOT BE RUNNING AROUND AND DOING THE INSURANCE COMPANIES JOB???
