Unacceptable Service

Due to terrible service I have decided to cancel my building insurance with ABSA. I have sent numerous emails indicating my intentions along with a copy of the new building insurance details. After getting no response to my emails I decided to phone through. 20 minutes I get through to the Cancellations Dept who inform me I need to give a calendar month's notice (fair enough) but they can't cancel it until the Vetting Department has called me, which takes approx 3 working days. As it is nearly month end, do I get penalised for another month if this so called Vetting Department only call me on Monday, which is then July. This is unacceptable and I would like this matter sorted out and my insurance cancelled without this song and dance!!!! I also note that on correspondence received today (indicating the increase on the policy effective September), there is a different policy number... so who knows what is happening.
