Argue with a customer?
.
No matter how right or wrong your reasons are, trust me again on this you can't win an argument with a customer. Normally, you shouldn't argue with a customer when handling a complaint.

Don't try to prove a point even when the customer is wrong, rather provide a solution.
If really you’re a professional then; stay calm don't take customers' anger personally(you are not the problem if you remain professional). Focus on the solution rather than the insult.

Anytime you try to prove a point it increases and escalates the unpleasant scene. Be focused and quick to solve the problem so things don't get outta control.

The keynotes are:
I won't argue with my customer..
I will focus on the solution and not the abuse...
The only point to prove is a solution..

Have a good weekend
