BAD CUSTOMER SERVICE AND NO RESPONSE ON ALL THEIR CONTACT LINES

I had since booked my flight tickets to Paris early 2021. I made a decision not to travel and asked for a refund. This is since September 2021, to date, No response on teh WhatsApp line, no answering of phone calls (i had to hold for 30minutes using my own airtime), No responses from their contact form. I am utterly disturbed by how hard I need to fight to get my refund back from this company without a dignity of a response. Failure to respond to this will lead me to escalate this matter to consumer protection because this is pure abuse of power and no disregard to peoples funds
