I used to work for sky. If you are not in contract with them,Call and ask to speak to the retention department. Tell them that you are needing to save a few quid and sky is a luxury that you can do without so you are THINKING of leaving sky. At this point you will be given an offer to try and make you stay with them. Refuse all of the offers until they tell you that they have nothing else they can offer then decided which ones is best for you. Some staff cut the bs and offer you the best one straight away but most will keep the best offer for last. Be polite and even have a laugh with them as this will get you a better offer. People who phone up and pee the staff off get nothing other than a note on their account saying not to give this account any offers as this person is a total (enter your preferred bad word here). Just make sure it is retentions you talk to as no one else has the authority to give the best offers. I hope this helps. X
