Geyser overflowing claim no:23_041508

I reported the geyser on Monday last week.,and standard bank promised to send someone the very sameday I requested half day at work. They didn't come and the next day I called a gain the promise the same thing saying the service provider called and did not find me, the problem is yes maybe they called why not leaving the message to say we are trying to reach you, we are experiencing loadshedding, there must be an alternative communication. . They came on saterday morning and they found out that the problem on the geyser is pressure valve.,and to buy that component I have to pay R1350. I said to them that I will call the office to find out if is possible for them to replace the whole geyser. The insurance said the policy does not allow them. And I bought the valve and the very same day I called the insurance to let their service provider that I bought the component till to day when I call they say they will send the service provider to communicate with me. I call every day nothing is happening when I call they say we will send the service provider. I'm stuck with the overflowing geyser Claim number 23_041508
