CAN NOT TRUST STANDARD BANK

I asked Standard Bank why since my husband had died 3 years ago and as I was still paying the bond I owed more now that I did when he died. Joseph Witticker from Standard Bank resolution centre checked it and I recieved an email back saying they had recalculated the bond and it was correct and as for as they were concerned it was over, I rep**** and asked what was going on and my email was returned saying it had been put on spam, No explanation or anything I am 72 and we have been with this bank since 1975 can you believe this.
