2023

February 2023

Renson contacted directly

Renson was contacted, and communication took place with Mr Goodman and Mr Maxim De Vriese. Subsequently, Mr De Vriese ceased responding to emails and could not be reached by telephone.

May 2023

Meeting at BAU Munich

At the BAU trade fair in Munich, Renson’s representative for Slovenia, Mr Maxim De Vriese, was personally informed of the matter. He stated that he had not received the message sent in February. As agreed, a new message and photographs were subsequently sent to him. Despite several follow-up attempts, Mr De Vriese ceased responding to emails and could not be reached by telephone.

2024

February 2024

Meeting with Ombra’s director

A meeting took place with Ombra’s director at his office. During the meeting, he asserted that Ombra’s work had not been paid in full. The client immediately confirmed that he was prepared to pay the outstanding amount that same day, requesting only the issuance of a handover report and a warranty certificate.

February 2024

Communication ceased

Ombra’s director asked for the matter to be submitted by email, which was done. From that point onwards, however, he ignored all further communication, stopped responding to emails and did not return any calls.

January 2025

Written summary sent to Renson

A further email summarising the full history of the matter was sent to Mr Goodman and Mr Maxim De Vriese.

16 January 2025

Second meeting at BAU Munich

At BAU Munich, the matter was again discussed in person with Mr Maxim De Vriese, Mr Dieter Pillen and Mr Dieter Bodwin. Mr De Vriese initially appeared to have difficulty recalling the previous communications concerning the matter. After the situation and its history were presented again, they stated that they would personally ensure that the matter was resolved by the end of 2025, which, given that it was only January at the time, provided more than sufficient time to bring the matter to a satisfactory resolution.
