O2 were working with a company called Business Mobile Deals.net which went out of business. O2 eventually took a lead and gave all existing BMD customers a chance to start a new 3 year deal which wasn't as cheap as other deals they were selling at that time sold through another satellite company called Anglia Telecom. Also they increase the annual prices by the most compared to other companies. Their customer service is woeful! Only able to be contacted by email. I would suggest any new customers read reviews carefully and then steer clear!! Since Brexit a lot of customer safeguards have been removed! You have been warned!!!
