If those that cock-up spent half as much time as they do trying to defend bad feedback and concentrated on doing the job properly in the 1st place, then no bad feedback would be left.
Feedback is there for a reason, to pat eachother on the back on how wonderful we all are, and what a pleasure it was covering the job for you, or doing the job on our behalf , thereby informing others that this courier or courier company is a "good egg" and one you can trust.
It is also there to warn others when things don't go as planned. We all have bad days, so if there is just one poor feedback as opposed to dozens of good uns, you see the bad un for what it is. If however there are several, then that tells a different story, and that is exactly what its there for.
I fully understand why you wouldn't want bad feedback to be left, but by far the easiest way of avoiding getting any is to not screw up.
1-Collect within the time frames given. If that is looking unlikely inform the vendor so he can do something about it by either giving him time to inform his customer or allowing him the time to find an alternative solution.
2-Deliver within the time frames given, If that is looking unlikely inform the vendor so he can either ask the recipient to extend the time window, or give an alternative address, or rearrange the delivery for another time.
That's basically it isn't it? That's all we ask as vendors, to collect when we want it collecting, and to deliver when we want it delivering. Anything else is just adding flashy bits to what is afterall pretty simple.
What you want to avoid at all costs is the vendors customer ringing up asking where the courier is AND worse still then being unable to contact said Courier to find out why.
THAT is why you get bad feedback, and that is undefendable.
And before anyone thinks this is a bit one sided, yes Vendors are equally required to give the courier as much information as possible. Company name, contact name, contact number, correct address, correct postcode, what it is they're wanting collected, ensuring the right sized van is ordered, to inform whether any loading or unloading is expected etc etc. And many many of us fail in getting even the basic information and make the couriers job so much harder than it needs to be.
So i guess what i'm saying is lets all be considerate to eachother, be professional about what it is we do, and if we mess up, put our hands up and make sure we learn from it and ensure it is just a blip on an otherwise blemish free feedback
