Bad Service

We booked a bus Ticket on the 30th January 2022, we never traveled and asked for a refund. All necessary documents were submitted on the 17th of February 2022 and were given a 21 days waiting period which ended on the 18th March 2022 and still no refund,no communication whatsoever. Another communication sent to Finance Supervisor on the 30th March as follow up but still nothing and today on the 20th April 2022 we have been waiting for an hour but no assistance whatsoever,we are given a run around. No communication means to Management and any other superiors is allowed.
