Refund related query

I am writing to express my deep disappointment regarding the lack of progress in resolving my refund for the graduation interview fee. It has been three months since my graduation interview, and despite numerous attempts to contact the support team, I have yet to receive any updates or a refund. Initially, I was asked to wait patiently for a few days, but as time passed, there has been no change in the refund status. It feels like I'm stuck in a loop, with the team repeating the same reassurances without any tangible results. I understand that delays can occur, but it has now been an unreasonable amount of time to wait for a refund. I kindly request that you stop asking me to wait patiently and expedite the refund process as soon as possible. Your immediate attention to this matter would be greatly appreciated.
