Totally inefficient

Started subscription but 2 weeks later & numerous phone calls no newspapers. Spoke to Joanne who promised to sort it out. Received one Sunday Times but no Times. She also promised to call but never did & now does not answer her phone.Called to cancel & since the cancellation have received several Times. Yet more phone calls but the latest one informed me that it takes 31 days to cancel. I give up. No one seems able or competent enough to help. How can they run a business in this chaotic & unbusiness like way?
