For a firmware problem my
For a firmware problem my bike hasn't been working for more than a month now. You sent a new battery that didn't resolve the issue, then told me you will send a new PCB, then that you don't know when it will be available, then that actually a technician can solve the problem without a new PCB, but since then two booked appointments have been cancelled and now your customer service doesn't even reply anymore. I've just lost a great deal of money in a scam, that's my opinion. But I won't let it go that easily, I'm ready even to sue you together with other users who received the same treatment if I don't get some refund.
