Well all's well that end's well so they say, ha,ha.
Any way when I received the replacement monitor they forgot to include the power & video cables plus the remote, no biggie as I have plenty cables hanging around but still, so I phoned them regarding this & their comment was that I should have kept the original parts from my old unit, to which I replied I would have but I was promised a new not a second hand unit, they didn't get that memo evidently, so they suggested I wait until they received my old unit & they would send back my parts.
1 week later I get a phone call from someone saying they have my parcel, evidently the courier got my address mixed up, at least the house was only 5 mins away. so I picked it up took it home to find that the cables where there but no remote.
Phoned AOC again, told them about the wrong address syndrome, he said he would have a courier pick it up & deliver it back to me in the next 5 days, I mentioned that I would do this myself as it's only 5 mins away, I also mentioned the missing remote he said that he personally packed the bag, but would double check & if found would send it to me ASAP.
1 week later no remote emailed AOC support HQ, received a reply the next day, again apologizing for the mishap & that they would speak to their staff plus check up on the courier service & would send me a 2nd replacement remote ( I don't have the first one!) in the next 5 days so I am thinking next Friday at the latest. (fingers crossed).
Ben.
PS, still no noise from this monitor so at least they got something right.
PPS. I also mentioned in the email that from day one I have been keeping a running tally of events on a forum. (plus all emails to & fro).
