Poor service

I bought a Russell Hobbs steam iron last year and i was told it had two year warranty. Now the iron is giving me problems and i called the store to enquire, i was told it one year. I went to the store and was told to wait for manager who was in a meeting. I waited till i decided to leave my number and they promised to call me of which they didn't. I called the store again yesterday and the lady said she is putting me to the manager, only to realize that she hung up the phone. I called 7 times after that, the phone was no longer ringing. I don't know if this the treatment they give to customers or it is specially reserved for us black people. I tried to follow the process but service i got is disgusting.
