The corporation offers vendingmachine support in the organization I work with. On 04/02 I applied 1 of the bill change devices (#4292) to alter a $5 bill. I just reveived $2.50 in groups in change. Per the info published about the device: I approached them at their e-maill address - [email protected], to see them of the problem. That same-day I obtained a phone from their store stating they'd deliver a compensation within the email that will take 2-3 months. On 04/25, when I hadn't yet receieved something from their store I approached them again by email, and questioned that which was occurring. They never replied. Though I've "read" email bills from somebody the email visited. I delivered another email on 04/28, & again on 04/30, neither which they replied to. Within the 04/30 email I advised them when they didn't react I'd be confirming them towards the accessible customer advocacy organizations. On 05/01 I also approached their parent organization - http://www.vtlgroup.com / - through their contact us web site - http://www.vtlgroup.com/contact.Asp & through their outlined email address - [email protected] I receieved a "read" email notice from somebody at their organization, but no reaction.
