Dear Mr. Pongsiri,
Hope you are fine. We received offers from two other Thai suppliers.
In fact they both offer prices much lower than your updated prices.
They are close to the previous prices you had.
Of course we do not want to switch supplier because we want to build a long-term relationship with you.
However, one condition is that problems should be solved correctly. We are currently losing money because of this rawhide problem.
We simply cannot accept a price increase that large because we will till bear the costs of the goods you are sending us for free.
Please understand and suggest a better solution to us. We really want to move on but we have to be compensated for the bad goods.
Please let us know what you can do.
Best regards,
Teun de Pont
