What to do if an error arises when ordering goods
Nobody is safe from errors. Famous postulate for all times. If an error was made, try not only to fix it, but also be sure to put your guilt.
A person will remember what you tried to do the last. And having received a discount on the purchase in your online store, he will definitely use it. It is not your mistake in his memory, but the fact that you not only corrected it, but also provided a bonus. Alien mistake? We will fix it.
The most common “someone else’s mistake” may be a carrier error. The goods can be delivered late or not deliver at all. You should not shrug your hands – not my problem. Try to send the goods to your client with a different carrier, and deal with the negligent yourself.
