Standard bank homeowners insurance

My home owners insurance was with standard bank for the last 9 years without any claims.l then found a new homeowner policy with less installments and less excess fees on the basic needs,Ibthen proceeded with giving my 30 day notice period to information centre at standard bank with my policy number and all other neccessary info for them to get back to me.

It's been 15days ago and I haven't received any feedback or confirmation or receipts of my query yet,so yesterday I phoned and was informed that the land line number has changed and I was provided with a email and all relevant information for them to able to assist me.My new policy will be activated from the beginning of September and not afford to pay double.

I just wish to get out of this contract please but whichever mails I send there seems to be no correspondent.
