    Worst service from O2. Been 6weeks and no one seems to be helping with my network issues! Ordered a replacement SIM card and now new issues happening. Avoid this company! They’ll take your money but not help when there’s a problem! @O2

    @O2 other companies have had price increases. I rang Virgin Media about my broadband price increase as it was also a new contract. They applied a reoccurring discount to offset the increase. Easily done. Happy customer = loyal customer. I look forward to leaving O2...
