We have just moved from Zurich to Geneva, taking our horizon box and modem with us. After 5 calls to UPC we still have no tv or internet working. No-one seems to have a record of our last call whenever we ring which is very annoying. The modem box shows the bottom light as green..sometimes it starts flashing and the word internet is also flashing. Can anyone help or tell is how we can resolve this asap. Thanks!
