Bad service

I am looking for a filter for a Bennet read vacuum cleaner from the 27 January 2024. Spoke to the area manager yesterday and he said he will drop it at my work place yesterday?? New day and still nothing. The employee are so rude and don't listen what you tell them. The one day the one guys as smelling to alcohol. You contact the head office and the same story. Ask for service department and the person is not available. Then you phone back ask for manager also not available.
