Useless towards elderly

I am utterly disgusting by them after absa handed my father who is 70 over to them he has made monthly payments to pay off his card with a payment plan that he made with them yet they continously phone asking him to make payments and sending emails telling him he is facing legal action if he does not settle the amount in 48 hours honestly you want him to settle it with the ****ing R1600 he receives a month from sassa i would love to see you ****ing do that
