If a vendor you are using is using Fastway, just say no

My parcel has an undefined “problem” according to the tracking on their website. I have tried contacting them through four different channels since 2 o’clock this afternoon (8 hours ago) and they have not responded to me. A simple “we are aware of the problem and are looking into it” would suffice, but they have chosen to ghost me. They do not deserve to be in business.
