Had a factory customer service call to help us with a problem. (RE-NO. 7142083).

The WKD had to move out several times, an accommodation for the missions without success - just as unsuccessful as the feedback on e-mails.

The first and second reminders went relatively quickly!

I did not receive an email from the customer service department today - there is neither a fixed contact person nor a telephone number for contacting the invoice.

Vaillant - VERY WEAK.

Even the field staff "supposedly" couldn't do anything.
