Terrible customer service

I need to cancel my Hollard home owners insurance can someone please assist me. I’ve been calling for the past 3 days asking for a simple statement with no luck, I was told a certain Nomfundo will call till date nothing has happened. My biggest fear is if it can take this company a whole week to attend to an enquiry what more when lodging a claim? What a red flag of an insurance! Please assist with cancellation asap unless you prefer me to reverse debit orders until the cover lapses? Please ngo moya we Sonto assist me.
