Standard bank

All Standard bank has done is demand payment where I was hospitalized for 5 months in 2016 after reporting . They added interest which is twice what I owe them and every month when I pay they dont issue out statements of my balance, all I get are calls from legal department, because I am avoiding a garnish I am paying, till when must I pay cause according to my records I have paid more than the required amount. Now I must get billed for statements....
