Poor service Discovery

We cancelled our Discovery Health membership last year. After several months we were informed that we owe Discovery Health money. We made payment and sent POP to Discovery as well Shapiro Shaik Attorneys on 7 March. Since then we have been hounded by the attorneys for payment although it has already been made. We kept telling them it’s been paid but they have persisted in phoning us several times a day. Why bother sending emails with POP as well as putting a reference on the payment if they DO NOT update their systems. Between my husband and myself we spend over R5000 per month on Discovery Life and Invest. This whole experience has left such a bad taste in my mouth that I am considering moving my policies elsewhere.
