NO REF NUMBER AND NO CONFIRMATION

I phoned on the 29th of Apr to cancel an insurance policy that would have taken effect on the first day of June. I was refused a reference number and told I will receive an email as confirmation. After not receiving such an email, I phoned again today with the same outcome. I requested a reference number, which again I didn't receive and again no email to confirm the cancellation.<br> <br> I also sent an email on the 28th of Apr via the website and received an automated reply which reads: Your reference number is *** and you can expect a response to your enquiry within 1 business day. I've still not received a response.<br> <br> Please send me confirmation regarding the cancellation of the policy.
