I signed up to an 18 Sky broadband contract with Sky in March 2023 for £25 per month, after my first bill they increase the contract price without warning to £29 per month, at this time their website was offering  the same deal at£27 per month. In August 2023 they increase my bill to £39.50 without warning! A whopping 58.5% increase from the £25 contract I signed up to 6 month's earlier. No explanation of this price increase, no warning, nothing! I've studied my bill their isn't any additional charges added for services not included just the"superfast broadband" package I originally signed up to priced at £25 per month. I have contacted Sky customer service about this & they couldn't care less! The only response I get is... Price increase from April 23. How can they legally sell me a 18 contract with a price increase after the first 30 days without a minimum period of notice or any form of warning? How can they legally increase my bill by 58% within the first 6 months of my contract? Again without warning. The customer service reply to this part of my complaint, Sky chose to completely ignore the 58% price increase! No response! My future bill from April 2024 will be £43.50 per month! the same deal currently advertised on your website for £27 per month (March 24) that's a price rise increase of 61% on my contact 12 months in to my 18 month contract.  This will be challenged legally! Your customer service response is disgusting! Your company are acting illegaly!
