Poor Service

It's been a month since Standard bank insurance came out and repaired a water leak at my house and was told by the plumber that someone will come to fix the paving that they removed in order to get to the water leak Since then its been a month no one has come out to fix the paving nore did any one call me, I've logged a claim 5 times and they keep giving me the runaround. I received an email stating that I should call the plumbers, the plumbers say I must call Standard bank insurance then when I called the call center the 6th time the call center agent said I must fix it my self and they don't cover the the leak by the meter although the meter is not a council meter it's a sub meter for a tennant to monitor usage and is inside my property. Standard Bank hasn't provided me with the claws mentioned in the contract that they don't cover the meter that belongs to the owner and is not a council meter this meter is an additional installation done by me and is an important to the property I've asked the call center agent if I could speak to a supervisor, was told a supervisor will call me back but no one calls.
