Refund from egyptair

Hello everyone

I have booked a ticket with egyptair on Sep18 and applied for refund on the 21st of the same month.

The refund was supposed to take 21 working days to be credited to the card used for payment. However, I have not received anything yet and everytime we contact the office they simply say it will be refunded and lastly they said we must send an email ,which i did but unfortunately to this day there's no reply to my emqil or any amount refunded .

Does it usually take longer for the airline to issue refunds or do they ever issue refunds? I'm afraid they won't refund me , the ticket was too expensive but I had no choice at the time. Did anyone have similar experience with them and what did you do?

Thank you in advance
