I went through an unspeakable ordeal after my two years contract with O2. My long held special number was deactivated while I was still on call with O2 advisor without an option to port my number to another provider. For week of calls, every advisor told me different stories. One directed me to buy a new sim and visit their shop to transfer my number, in the shop, the manager was very rude and she could assist. Today, I was transferred on call to four different advisors with each asking sets of security question, after about three hours of interrogation, I was left unattended for about 45 minutes and timed out. Imagine the lost of business revenue, connection with family and friends and access to other services registered with that number. In my view, O2 is insensitive, deceitful and lacks credibility.
