Hollard Funeral / Mahala: horrific service

I've had awful service from Mahala, who are underwriting for Hollard, from day 1. During July I took out a funeral policy for my mom. I noticed that the premium never went off my bank account. Followed up with Mahala - challenges of working from home to blame (unacceptable excuse - we've been working from home over a year) - emails attempting to resolve just ignored. Finally sorted out mid August. After much complaining got them to make policy effective 1/7/21. Now I need to cancel the policy. Mailed the manager who'd dealt with my application on Friday - unsurprisingly not even a response. Have been emailing the address I was given by their reception since Monday morning - once again no response - only ack knowledgement of receipt which is useless.
