Old Mutual Gap Cover - Non Existent Communication!

Disgusting service (or should I say lack of service) from Old Mutual Gap Cover. Unaware that things had changed, I submitted 4 gap cover claims in early March. For each submission to ***, I got an automated reply thanking me for my email and saying they would contact me in the next 3-5 days. Nothing happened, so I emailed them again, and copied the *** - again no response, so I emailed AGAIN. I then went overseas for two weeks and on my return I checked, and STILL zero response from either email address. Knowing that there was some relationship with Kaelo, I phoned the Kaelo number and was told "Oh no, things have changed and there is now a NEW email address and claim form". These were sent to me by email immediately and I have now resubmitted the claims to the new email address. My gripe is - why could Old Mutual not have advised by email that things were changing? It seems they did nothing! This is very poor service!
