Poor customer service experience

I have logged a dispute with transition on 11/01/2021 and have not been able to follow up. I have received an sms stating that documents, which has been uploaded when the dispute were logged, should be faxed to them with no other alternatives like an email address provided. Who has access to a fax machine in 2021? Poor customer service experience. The only contact details provided on the website is a share call number and the calls are not being answered timeously, I ended up ending the calls as I held on for quite a long time. The online support contact application is not operational, it constantly respond with an error "Please complete all required fields" when all fields are completed. It is an impossible task to get hold of the company to get assistance and my matter has still not been resolved.
