Phone Harassments

In the past couple of months it seems that Standard Bank is on a mission to irritate its customers as much as possible. I literally get a call every day from Standard Bank Homeloans dept. about my home loan. They claim I am behind on my payments, which is not true as I pay my bond every month. What is more interesting is that the amount I am "behind" changes constantly. Now here where it gets more interesting, it does not matter if you tell the consultant what the story is( I reached an agreement with Standard Bank about 2 years ago) the next one calling you has no record of what was discussed the previous day. I responded on email to Phindile Ndaba - and guess what...No response. I have also responded to this email: *** with no response. Then If they can't get hold of me on a specific day, I get a threatening SMS. I have been a Standard Bank customer for approx 40 years but get treated like a common ********. These phone harassments is not acceptable.
