No delivery from Fastway Couriers

Parcel promised on 16 December. Told usnthey tried to deliver - we were home - no intercom pressed, no missed phone call. On website - for contact, same message keeps appearing - could not speak to an agent. Was contacted by email to confirm details - so they have my email, my cell number, my husbands cell number, my address. When I rep**** the second time to email to ask for ETA, email address would not accept my communication. Tried to contact on main number - for 11 minutes, no answer. Tried couriers number for our area, was told to contact main number. I am now trying to contact CEO...parcel is 3 weeks late and tracking number is now no longer working. Very frustrating
