Genesis steam iron

Besides their service, their products are the worst ever! On 4 th September 2018 I bought a genesis steam iron. On 25 November 2018 it was exchanged for a new one due to no money back policy. On 18 February 2019 I had to go back once again for the exact same problem..... a faulty steam knob. I can't get my money back, as from the shop up to Head Office, everyone tells a different story. No product can last only 2 months and 10 days. First I was told that it is a reject, which one can understand.... to a certain extend but twice????? Nope, that does not do the trick.
