3 months waiting for my refund

I bought my ticket bus ticket at shoprite with Eldo coaches which has stopped operating since 20 June, i bught my tickets beginning of May, they did not bother communicating with customers to arrange alternative transport for them on time or refund us ,I only found out they have suspended their busses from dbn to jhb when I got to Durban station. The ill-treatment on their whatsapp is appalling. They blocked me because I was "rude" I asked my mother to speak to them and they last said my refund is in cue they have a backlog at their finance department. After reading the stories on hello peter it seems I will never my money back because they dont even reply back. They are ******* and a bunch of unprofessional individuals. If there is a way to seek some help please let's share so that we can get out monies back. Their whatsapp number is no longer working, where can I get them physically? Because the purchase was done with computicket this is where I need your intervention and assist us. I bought my ticket with computicket therefore it is only rightful that you reimburse me and you can claim it from Eldo Coashes.
