Avoid XLN. Nothing is excellent there. We contact them many times trying to reduce our bills because we no longer use their services. We moved into a different office with broadband and telephone lines included in the rent, so we do not use XLN anymore. They do not care about you, just want your money even they do not provide any services. On top of that, as we are a long period customer, they rise our bills without my consent. Now we have to pay nearly £70/monthly for nothing. Customer service always said sorry, we can't help you. Avoid XLN. I’m sure that they push their employees or pay third parties to write reviews to keep their ratings up.
