Firstly, please note editing your listing will decline all current active quotes. This is because your quotes may not be accurate according to the new details.
Should you need to make major changes that will affect the possible quotes, then you should do the following:
Navigate to Listings & Bookings
If you already have active quotes on your listing, but wish to clarify small changes (such as small changes in dimensions, weight, dates) with a specific provider, simply expand their quote to see the Talk to box (seen below). Here you can communicate with the provider without declining any quotes. Please note you can't share any personal or business contact details in this section.
