On 16 Jan 2023, I signed a Volt G1 Fibre Broadband contract for £34 Monthly. Today I logged into my virgin account and to my surprise, Virgin unilaterally changed the arrangement and demoted me to a Volt M500 starting from 11 of Feb 2023 for £33 plus an additional bloody £5. Is this legal? Can I take legal action?
Please help as I am frustrated with them
Of course they can't, any more than you can one-sidedly change the contract, for example by deciding that £15 a month is what you'll pay them. Forum staff should be able to sort this out for you, if they won't then we can explain how to take matters forward in a way that will force the company to honour the agreed contract.
