Disapointed by the poor service

I was debited with insurance by Wesbank and 5 months premiums collected. I provided my details on 29 October and still to date the matter cannot be resolved and my refund processed. I have only received 1 premium refunded with no explanation why. I must say I didn't expect this kind of service from Wesbank and as I know they pride themselves in delivering excellent service but not this time. I gave them ample opportunity to correct this prior to airing their dirty laundry but to no avail. Hopefully now I can get your attention and action.
