Bad service, not wanting to pay Refund and no feedback

I have ordered a ticket for my husband from Eastern Cape from Eagle Liner, however He could not make it. I requested a refund on 27 June 2019. They responded saying it takes about 15-30 days. I was patient till end of July but still nothing. I have tried making contact with the offices and all they say is they will get back to me. We are halfway thru August and still no feedback. I feel that this is the worst service and experience I have ever had to deal with.
