Terrible Service from Nedbank

We took out a home loan with Nedbank a year ago, at that time we chose not to use Nedbank insurance for our building insurance because we got a much cheaper quote from an external insurance provider. We sent through proof of insurance to Nedbank at that time. Nedbank has however been charging us for insurance for the last year, although we have been paying the other policy as well. <br> <br> Last week I phoned Nedbank insurance and they assured me that if I sent them an email with the proof of insurance thye will reimburse the premiums paid over the last year and cancel the insurance policy. After sending them an email and waiting a week for them to respond, they only reply to my email with a generic email on how to cancel my insurance policy. It seems that the person responding to the email didn't even read the mail.<br>
