I did read the case, if it's the same

Usually, I wait some days before removing a service:
The reason is it deserves to give time to mixers since we all have a life outside, it may take time to check what happened and the users complaining may come back several days after to tell us it's ok or never come back.

I practice this way, especially when I feel it's an isolated case. Of course, if there are a dozen people complaining in the same period of time, there is no question to wonder.

I also know that some people try to make others believe that X or Y mixer is a scam when it is not true. It even happened that I tested the blender myself to verify the claims or the (baseless) "rumors"
