failure to honour appointment

twice this week mark has made appointments to come to my home to inspect a bed set we purchased 3 years ago - the bed planks squeak annoyingly which results in us getting little or no sleep. on both occassions he has failed to show without letting me know he cannot make it. i do not have his cell number to contact him to confirm the appointment yet he has my number to let me knoow he cannot make it. the bed set cost us around R18000 and after 3 years we can almost not use the bed due to the disturbing sound when sleeping on it. i think this is very bad service especially since he offered to come out and inspect the bed when i mentioned it to him on the occassion when we were purchasing a double bunk set from his store for my grandsons room which incidently was also delivered damaged and had to be replaced.
