Unanswered calls on the call center, holding for more than an hour for a consultant

I took a funeral cover with standard Bank insurance for my aunt and the lady who was assisting me captured the name wrong, I noticed the error as soon as they sent me the insurance policy documents I then tried to call their call center, they have never answered it just rings and put you on hold for the next available consultant for more than an hour. I've been trying to get hold of them for more than 3 weeks now but still no answer, I now want to cancel this policy because if it is this difficult to get assistance for such a small issue what will happen when it's time to claim.
