Unacceptable and unethical. I raised a complaint about fraudulent activity, but after two months, no action has been taken or inquiry made. I contacted O2 five times by phone and twice by email, yet they have not responded or resolved the issue. This reflects poorly on the company's business ethics and suggests misuse by their staff. I do not have any contracts with O2, nor have I applied for any products or services from O2 or their suppliers. Someone used my personal details to create two accounts with O2. Despite raising a complaint, O2 has not supported or investigated this fraudulent activity. Please be aware of O2's lack of response to such serious issues.
