Unsuccessful waiting period waiver & policy cancellation

On the 31st August I took out a funeral plan with Hollard. I then realised that I would have to continue paying Hollard and my current insurer for 6 months because of the 6 month waiting period and that would be fairly steep. At the same time I cannot cancel my current insurance and risk not being covered for 6 months.

I called the Hollard call centre the following day to enquire about the waiting period waiver option that I had seen with a competitor and was instructed to send an email requesting it to customer care. I have been waiting until today for either an email response or phone call and I received neither.

So I decided to call the customer care number today where I was sent from post to pillar. The last guy I spoke to hung up on me. I would like Hollard to inform me whether they are able to waive the waiting period. I included on the email the details of the policy I will be cancelling if Hollard approves my request. If for some reason, they cannot, I kindly request they cancel the policy I have with them. Policy number included in reference.
