Disgusting BA*****T company

I have a outstanding loan with Standard Bank, for a reason I don’t know they have handed my account over to these people, I have made my agreed payments to this outstanding loan religiously every month with no fail. Now I have These call centre agents calling me every two seconds to remind me of my debt. Ive spoken to them before and told them what my arrangement with Standard Bank is. I made a payment on the 23rd of march earlier than agreed. The entire weekend of the 30th I receive sms stating I have not paid I then email a proof of payment to them and a follow up email stating ive sent a proof of payment. On the 2nd of April I get a call from a call centre agent stating I have not been honest and not made a payment to them. After I informed her I have paid she says their system might be faulty. My issue is how does one do a job with a broken system communicate with Standard Bank and get your Sh*t together. Stop harassing the client that is paying. This is what one refers to as a ba*****t company they don’t have anything in order. I am most definitely going to take legal action against this BA*****T COMPANY. My debt gets paid every month I fell behind because life happened not because I didn’t want to pay I physically couldn’t. Rather go after people who blatantly refuses to pay instead of harassing people who do. From now on if they want to call me they can call my ****** lawyer. One of the worst companies I’ve ever come across what a embarrassment. Clearly Standard Bank has no standards
