Financially abusing elderly people

I’m writing on behalf of my aunt who is 78 years old. My aunt closed her account. We drove all the way from the Eastern cape rural area to Bloemfontein loch Logan Edgar’s. They said she must call head office and she did and canceled her account. Now she has been getting statements that say she owes and on that statement it just says fees, it doesn’t even state what the fees are for. Edgar’s is ****ming elderly people. She can’t keep paying for an account that she canceled. This is financial abuse towards the elderly.
