Mr Price doesn't attend to their customers

I had a query with Mr Price, a double payment was made to my account on the 26th March to date I have still got no assistance but they expect me to pay them meanwhile they have not rectified their mistake. It's frustrating because we are all in financial distress because of the current state in the country due to lock down!!!!! I've been on Twitter and facebook trying to get the matter sorted, I've emailed my bank statement and everything that was requested but nothing has happened
