I'm working for a led factory. one Iran customer has been chating with me for over three months.
Every email to me are full of items of all led lights and I always answered with patience.
At the stage of sample order, he asked us provide free samples and only agree pay for the freight.
OMG,I report to our CEO, he agreed. Then I just told him the freight fee.
instead of thanksgiving, he doubt I overcharge him the freight fee. It's just 800RMB.
How to handle this type of customers? I just can't help get angry.
