Dear Felix
Please note that we have received your order for 100 units of our Vector A2. Unfortunately, the price quoted you by our sales representative was not correct. Price increases by our suppliers have resulted in a higher unit price for the A2 series. The sales representative was made aware of the change in price prior to your order, but failed to pass the information along to you.
I apologize for the error on our part. However, we cannot ship the order until we receive payment for the difference. Please call me at (011) 6555 6555 to let me know how you wish to handle this matter.
Regards
Lydia
