Thanks to Matthew (possibly in the billing team?) Who helped me out over the phone with a query about my bill being wrong and also helped me switch to a package that's better for our needs. He was personable, friendly, funny, and a credit to Sky - unlike William on Twitter whose tone was rude and abrupt and who told me to cancel my Sky services if I was unhappy, rather than getting advice and help with my bill!
More of your customer service advisors should be like Matthew. Thank you! 🙂
