Disappointing and disconcerted Ex customer

Recently lodged a claim, which was incorrectly assigned, mind you the call is a daunting one as you will hold from being transferred from one person to the other. My invertor for solar blew suddenly and stopped working, upon calling them i was sent a plumber for my claim which i had to call back to the call center and then resorted to emailing. I had to email to follow up on the claim as there is no constant communication in regards to the claims. I then received an email from their third party noting the claim was referred to to the insurer for possible rejection ...this one reason stood out for me no peril at play???? the fact that the invertor blew was a danger on its own as much as im not an electrician i knew something was wrong and because we have been paying for an insurance for almost 10 years we thought lets claim as the invertor had just past its guarantee time...but then again on top of that we are told its wear and tear and we should pay that out of our pocket...Sooo it means we have just been paying an insurance for donations sake because when we need it, we told they cannot pay...OOOh the claims department is just a nightmare because even for us to get the letter to tell us about the regret, we had to call and find out what was taking long for a claim lodged on the 18April to be still dragging until May...I am disappointed and somewhat defeated on how this whole claim was handled. its the 09th of may i am still receiving sms about a plumber for our claim.....
