My computer started screaming . I had to remove battery to turn it off. . This happened a second time. Reimage add turned up , so I gave it a go.. Then the fun started. First the add was for NINE POUNDS, STERLING. (speaking to India ) I was told TWENTY NINE POUNDS. Within minutes that had risen to TWO HUNDRED pounds.. Had to call back This time the PHILIPEANS. AN angry little runt by the name of Fernandez ,shouted down the phone... I had not even spoke a word. then he slammed the phone down. He did the same again , even though I told him to listen to what I wanted him to hear., A third time I spoke to a female ,,who listened and understood I was not going to go from NINE pounds to TWO HUNDRED , SHE got my TWENTY NINE pounds on refund within seven working days.... we'll see … I will buy my security from a shop from now on.. The female is the only reason I gave customer service a two ,otherwise it would have been a zero.
