Behaviour of ****mers!

I have made use of Payflex numerous times, with no issue. Until it was time to receive a refund! I noticed that my cell number needed to be updated in order to process the withdrawal from my wallet and add banking details. It has been 4 days of back and forth. I have been emailing, sending Whatsapp messages, and attending to the numerous requests to verify my identity via Curata. I have done this, numerous times over the course of 4 days. Today, I receive a response that my image is not verified with Home affairs. Imagine! I do not have the new ID cards, and yes, I am a SA citizen using a green bar coded ID still. This is an acceptable form of identification throughout the country, across all institutions. It is amazing how Payflex is able to deduct money from my account for over a year, on time with no verification of image or ID. As soon as funds are due to me , I must jump through hoops, only to then receive a blatant ,sorry we cannot help you. To make matters worse, the support contact number listed is constantly busy. It does not even ring. it goes straight to voice prompt that says they are too busy to take your call. (+***4) This is now appearing to be the behaviour of ****mers! I cannot speak to anyone. The Whatsapp line says to email, the very email address I have already been using all week. The email line says sorry, we cannot assist! What are my options? I want someone to call me and verify my details. There should be an alternative. People change cell numbers all the time. It cannot simply be impossible to change my number in order to receive my refund. Call me Payflex! I want my money back.
