Encountered a comparable situation when I canceled a flight with Avianca. The refund process was opaque, and customer service provided little assistance. I found some insights on avianca where others shared their experiences. One user mentioned that after persistent follow-ups and documenting all interactions, they finally received their refund. It seems that being tenacious and keeping detailed records can make a difference. If you’re still facing issues, consider escalating the matter through official complaint channels or seeking assistance from consumer protection agencies.
