Difficult to know where to start. If you doubt the validity of all of these complaints about O2, simply try for yourself. Try and navigate their website or try to get help from their on line chat for anything other than a sale. Try ringing their help line, again for anything other than a sale. The poorest service I have ever experienced. I'm leaving them and will pay the penalty for early termination rather than suffer this poor level of service. You have been warned from a soon to be ex-customer!!
