Has anyone successfully ordered the Gen 3 wall connector through a service centre? I have some credit applied to my Tesla account that I wish to use to order the 3rd Gen HPWC, but I have to go through a service centre (can't order myself online and apply the credit). The guys at Oakville SC say they don't have a part number and can't order the HPWC for me. Was wondering if anyone else has done this (for Gen 3 only)? Thanks.
