No Response from FNB

I took out a new homeloan from FNB.WIth the homeloan I needed property insurance. When the bond was activated , FNB send me a letter with their insurance company activated on the homeloan. <br> I requested FNB to change the insurance to my preferred insurance company. I had to fill in forms and followed every step requested from FNB. I received a sms to say the query was resolved and everything was updated.<br> On my first debit order that went off exstra money was deducted for the insurance that I initially cancelled. I phoned FNB and they said the money will be returned as the insurance was cancelled. Fnb said this will take 7 days to be resolved. Again I received an sms saying the query was resolved. The next month the insurance money was deducted again. Went through the same process and yet its still not resolved. I have doubled paid for insurace for 3 months now.
