Service providers taking too long

I logged a call with OUTsurance for a claim Monday(29 January 2018) evening regarding a leaking shower, the claim was for Home insurance. They said they will send someone to come fix the shower. The service provider came on the same evening to catch the leak, he didn't do anything as he mentioned that the fixing of the pipes in the shower are beyond his scope of work. He left and said he will send someone else. The following morning, a leak detector was send to my house of which he couldn't do anything and he called the contact centre to let them know that they need to send a plumber. No one was send, the shower is still leaking and this is running a huge water bill for me.

Can you please send someone who actually knows what they need to do as I cannot have water running non-stop, this is adding to my water bill.
