Spent over 30 minutes with call centre who seem clueless and keep passing the buck

Went to the Standard Bank Branch who telephoned the call centre of Standard Bank as my home loan account ********** 29 was all of a sudden charged on the 02 September 2017 with an amount of R280.06 plus R90.27 for an insurance premium that I did not authorise . I sent over half an hour on the phone with consultants that seemed clueless on the 11 September 2017 from 11.55am to 12.30 pm and therafter was transferred again to an automated claim centre .

My contention is that the insurance premium for the building structure is already included in my monthly instalment of R13 781.80 and why am I being charged again seperately on the 02 Sept 2017 R280.06 plus R90.27 . The consultant at Standard Bank Insurance agreed that the insurance on the building structure is already included in the monthly instalment and than transferred me to a home loan consultant to sort out . This home loan consultant seemed clueless . She said yes it is included in my instalment and that the amount showing on my home loan statement is not actually charged to my account . I tried to explain that it has been charged to my home loan account which means a duplicate payment for building structure insurance . I did not authorise any other insurance . She than said it was insurance because I app**** for an access bond facility . I explained her that no one explained that there would be an additional insurance charge if one applies to link the bond to a card . We went in circles for a long time and than she wanted to transfer me back to the Insurance dept which I refused as I had already spoken to them and was now over half an hour on the call . She transferred me anyhow and I was than put on an automated insurance claim option . I gave up in frustration . My issue remains unresolved and my home account remains charged for an extra amount of R280.06 and R90.27 which is already included in my total monthly instalment . Standard bank needs to reverse this and also refund me the interest charged on this . My time was totally wasted and standard bank shows no regard and respect for their customers time by placing consultants who are so poorly trained . Please check your call centre records for the time period 11.55 am to 12.30pm . I know the calls are recorded . The call was made from Standard Bank Brixton Branch .
