  • ewanwhosarmy Tinkerbell52 (@ewanwhosarmy) reported

    @O2 Would love to add another phone to the contract - but call waiting time is 30 minutes. So waited. Then menu doesn't work: stuck in "for sales, press 1.... "whatever I press, it just repeats options" FFS - You're a phone operator who can't operate a phone.
