Struggling to cancel a policy within the 30 day period

I had a policy underwritten for life cover on my new home. Before inception date I discovered Metropolitan was quoting me R1000 more than other insurance providers. I called and spoke to the manager of the consultant Leonie Kotze, and requested a revised quote. He said they can't so I requested. Cancellation since it was within the cooling off period and I could get the cover cheaper elsewhere. He verbally assured me that it would be canceled. I emailed a few days later and still no response. A debit order has just went off my bank for this enormous amount and I'm desperately trying to get someone to adhere to my request for cancellation and do a refund. It is concerning to read all these negative reviews and then be inconvenienced by a company that is so desperate for business in these difficult economic times that they just ignore you when you tell them their product offering is not on par with competitors. Come on Metropolitan Life... Do the right thing. Give us our constitutional right to CHOOSE BEST PRACTICE... You are certainly not it and your incompetence to abide by your promises is testament to that. I look forward to be proven wrong.
