I don't even have O2 yet the Debt Collection Agency continues writing to me stating that multiple accounts in my name were in arrears and I owe them money! Obviously fraudulent so reported to O2 the 1st time ... then the 2nd ... etc. Even though the Fraud Team said it had been sorted and details blocked, received another letter for a different agreement number and amount from the DCA demanding payment(s) again!? Was later sent a generic letter from the Fraud Team I have heard NOTHING from their Complaints Team when I cited concerns, particularly on my credit record. Would have thought that O2 would try everything to protect their reputation in light of reported criminal activities? Given their inability to manage serious issues or basic customer engagement, AVOID AT ALL COSTS!
