They do not pick up the phone

I am trying to get my excess payment on a claim to be refunded for more that 12 months already and has tried to speak to somebody in the Standard Bank Insurance Legal Department about it. They just do not answer the phone. My Reference for claim is 408220. The Call Center keep referring me to the Legal Department at *** but I get no answer. At this stage I am ready to take my business elsewhere but that will mean that I will never see my R2000.00 again.
