Punbus / Punjab Roadways — Regarding my refund due to change of bus from their side

Due to a change of bus for some reasons from their side On 6 July 2022. I am unable to board the bus. I had booked my ticket from Chandigarh to Delhi through the pun bus app and my PNR NO. is[protected] and the departure time was 9.35AM. I asked the executive sitting at the counter when I will get my refund and he said it will be in 7 days. I called him after 6 days and asked the same question and he told the same old answer and then I have been calling again in the office for the past 2 days but nobody is picking up my call and also called on the refund helpline number. It's been 12 days and I still haven't gotten a refund on my account. I request you to inquire on this matter and help me out with this problem and refund my money as soon as possible . I shall be very thankful to you.
