We are a manufacturer in Long Beach CA. It is important to us that our machinery is operating correctly. When one of our machines required a replacement part, we ordered from Mara Industrial Supply. Our replacement part was to arrived UPS ground within 5 business days. On the 6th day, we started calling Mara to inquire about the status of our order. We were not able to reach a Mara representative until day 8. The Mara representative stated charges to our credit card had been reversed as Mara was out of stock on our part. We stated a confirmation notice from Mara was received on April 1, indicating the part had been shipped. Our order was originally placed in March and our machine has been out of operation since then. The Mara representative was unable to offer any suggestions. I asked to speak to a supervisor or manager, he was not available.
