It did take about 2 months to get it sorted out. I had to phone and chase a number of times, and there was a few challenges at the end due to Vanmoof getting an invoice conversion wrong (in my favour) so I had to change the total amount of the loan, however that actually wasn't massively hard bearing in mind the amount went down. The main issue was that they seem to have based the whole process on buying a car so I needed to get a "quote" from my supplier which is pretty useless for many places. I actually just bought and paid the deposit on a bike and used the deposit invoice as the "quote" in the end and they didn't seem to have an issue with that.
I did give them extensive feedback after I sorted it out finally.
