Worst after-sales service with empty promises and very bad communication

Dear KLM / Air France: Can you please confirm for us why we have been waiting for almost 15 weeks now without a refund. Please see details of this situation below. We are not getting any feedback and clearly KLM / Air France likes to hold people's money in their bank account as long as possible so that they can generate as much as possible interest on our money. You guys have been sitting with our money for 14 months now. Seriously???? Flight *** These tickets were booked on 29/11/2019 We were issued vouchers for the two flight tickets (4 flights) and 4 baggage tickets on 10/03/2020, as the world went into lockdown. I phoned Air France South Africa on 19/10/2020 and was told that we will be able to receive a full refund on the two flights tickets and 4 baggage tickets, and that repayment will happen on the credit card used within 8 to 12 weeks. This refund request was submitted, and this was confirmed by the call centre just now, as showing on your systems It's been almost 15 weeks now and no payment has been received. And no feedback being received from your refund department. ****** poor
