" all kind of unforeseen"???
I never got any email informing me about increased price , that is not true.
You know my tel number ,vey well.
What you are saying is that you guarantee price on invoice for 30 days.
The fact is plain and simple - you increased price which you put on invoice when customer showed up in your shop to pick up order, customer expected to pay that amount.
You try to justify ...
there are at least 2 people here who agree that you breached contract of invoice - invoice is a contract you see. No matter what cicumstances, if I drove or walk .
BOTTOM LINE : I did not expect no way in the world to pay more than on invoice.
BOTTOM LINE: I put 500 dollars deposit.
Now you have a business which accept deposit and when customer come to pick up what he ordered business increases price.
Leave other details out
