Tevo bad service

I bought a bennet and reed wet and dry vacuum cleaner about a year ago. I needed to replace the filter but none of the agents for tevo stocks the filters anymore. I have exhausted all efforts to buy one, Surely tevo can stock the filters for a year after discontining a product. So what do we do ??? Throw it away, and by the way there services are terrible dealing with people. I will not recommend anybody buying tevo products 😡
