I have been a faithful customer of BBB for over 20 years and used to give them 5 stars gladly. Not any more. They now use COVID as an excuse for poor customer service and poor quality products. I purchased a vacuum robot from them which was defective, another defective one was sent as a replacement (or maybe the same one, it displayed the same problem) and now I have been waiting for another replacement and instead I received a refund without any explanation. If you try to call/chat the waiting time is over an hour (70 minutes is now their "standard", in reality it can be more). The email option seems available on their website but if you email you get a response that email is not monitored because of COVID, so you've just wasted your time. So Customer Service is practically non-existent. BBB has become a source of frustration, they will lose their customer base with this attitude. I know I am one of them, I'm done dealing with BBB.
