It definitely wasn't easy tho man...
I have called them up 8 months ago, was rejected even though I told them I'm with SAU and it's a CAMS affiliated club and they said call back when you are 25.
As my insurance got closer to end date, I called Shannons again, the dude said that I tried to get a quote 8 months ago and they rejected me, and he said to call back after a year since the quote was rejected. I didn't give up though, called back 5mins later, spoke to a different guy, I told him I wanted a quote and he said I did have a rejected quote but meh LOL, he deleted my profile and started a new one and gave me a quote for $1669 for $18,000.
And just the other day as I'm about to get the policy, I wanted my agreed value to go higher, so I called up and asked for it..
So that's my journey with Shannons lol
Fail once, twice, 3 times, just don't give up, keep trying until you speak to the right person lol xD
