AVOID AVOID AVOID. I had a call from someone claiming they worked for o2 offering me a cheaper tariff which i accepted but turns out it was somone fron aerial direct switching me over to their company and signing a contract without my permission!! And then for this tarrif to not even work on my phone, every time i phoned to sort this they kept telling me to wait 24 hours and of course nothing happened. I then spoke to a manager to close my account, i done this within 2 weeks so was in my right to cancel but he laughed on the phone and refused to cancel im beyond fuming. I honestly dont know how this company are in buisness its disgusting to see theyre doing it to lots of other people aswell.
