I received the wrong brake booster, phoned them then sent it back a day later for the right one. That was almost 2 weeks ago. 3-4 days ago I sent an email asking what has happened to it, no reply. Sent 2nd email, waited 2 days (?), got a reply saying the booster I sent back has been received and the right one (hopefully) should be here in a couple of days. Lets hope so!
