No SERVICE once again

I have been calling Std Bank HOC for the past month. Accessors came out and thumb sucked a problem and declined my claim and left. HOW DOES a CORPORATE INSTITUTION work like this. I have since been calling to tell them that I got plumbers of my own to fix the problem as well as the damage they did not want to cover and the plumbers advised that it was not the drain which STD BANK insurance explained it was and declined my claim. WATCH OUT FOR STD BANK HOC....they never call back on their "WE WILL CALL YOU BACK" line and I messages Merlene Ogle which a consultant asked me to do to escalate and NO ONE TO DAT has come back to me - STD BANK IS SICKENING me with NO SERVICE ...
