Failed Collection When I Was Available

I ordered a Gear S3 Frontier and the sensors stopped working after two weeks. I logged an exchange which was handled quickly and efficiently.

However, the collection was scheduled for today (4th June) before 12:00. I just received an SMS saying they tried to collect but couldn't.

I've been sitting at my desk ALL morning waiting for them to arrive.

NO ONE came and they just say they couldn't?!

Now I am inconvenienced and have to move out other meetings as I have to wait for you again?!

Clearly your couriers are getting severely lazy.
