KLM After-sales service SUCKS!

If I could give KLM a negative rating I would. I recently had my flights cancelled due to KLM's suspension of long haul, Covid related. I'd purchased Extra Options on each flight for Economy Comfort upgrade and, obviously, would like refunds. KLM do make refunds available for these kinds of transactions, however just this once KLM didn't provide the EMD numbers for the transactions and so this refund facility isn't available to me. So I've been trying to get the EMD numbers. The only way you can contact KLM is by FB Messenger and WhatsApp, and by phone - but international phone call is just not going to do. The Messenger and WhatsApp agents restrict their communications with you to about once per day, and their quality of service is zero. They constantly stonewall with circular questions, repetition and refuse to allow you to engage at a higher level - total gatekeeping. Just another huge organisation that has no interest in after sales service or bothersome issues from its customers. Disgraceful. Fortunately I have now been flying with Lufthansa and will continually to do so.
