Worst Service!!

This has been my worst experience with a courier service ever! Last week Wednesday my package got delivered to the wrong address, admittedly not RAM's error. The driver told me the office will phone me to change the address, which they did not, but diligently I log onto their website and logged a ticket to change my delivery address, I still have not had any further comms on this ticket. (also the link in the email to follow the ticket doesn't work). I then phoned them on Friday, after the first call was answered (10mins later) I was on hold with an agent for 15mins with no feedback. So I tried again, 2nd call answered after 15mins and again on hold for 5-10mins I eventually got hold of a supervisor. All they could tell me was the ticket was not actioned and they promised to phone me back that afternoon. Guess what it's now Tuesday and I've still heard nothing!!! AVOID using their services if you wan to keep your sanity and actually receive you parcel!
