It is for Dr Lindenberg. We purchased chairs and desk 9 Sept 2021. We need to exchange the plastic chairs. We send email - no response yet. Is there no other way to get in contact with you. The 087 nr stays engaged. We also could not see when we logged in, where to ask for replacement of the things we ordered. Really - please call Marie urgently on [protected]. We are a medical practice. We need chairs. Very urgent.
