Been with Onecom for a few years now, never had an issue until renewing with them earlier this year. They managed to sneak in an additional data line charging me for the privilege, even though I had unlimited data included within my new contract. Argued this with them and they eventually cancelled, but not letting me off the 30 day notice period that I still needed to pay for?! Also billed me for Spotify when it was included within my agreed entertainment package that I was already paying for. Extremely unhelpful staff when speaking to them over the phone, via e-mail or via chat. Am looking forward to ditching this robbing third party and going direct to Vodafone or O2 and dealing with people face to face. Definitely avoid this company like the plague!!!
