Request for quotation was answered relatively quickly. We also responded quickly to queries.
But when the contract was signed and the system was paid for, we started.
We do not respond to inquiries by mail. The delivery date was only met after a cancellation (by registered mail) was threatened. Goods were delivered without registration.
An appointment for the installation has been agreed. The system should be installed 6 weeks later on Monday. 1 day before the installation we were informed by email that the date had to be postponed by 5 weeks. Of course, nobody can be reached by phone, no response to emails either.
Asked directly via the installer, thereupon the appointment was only postponed by 14 days.
The deadline was then kept. I have to say the assembly company worked cleanly and quickly. There is nothing wrong with that. Praise to the two fitters, went great.
