Cancellation of security cession takes ages

I went to our Sanbel branch in November to get my security on my policy cancel the lade Karen told me it would take some time about 3 weeks to finalise. well this is now 14th January 2016 and I already called from last week and the cession still not cancelled. I wont be able to receive the proceeds on my policy before this is not finalised. They said that the cession is already cancelled but I checked and its still not cancelled at the life insurance company. so how long will this still take???
