I ordered a Sim card as an additional line. This sim card never arrived, I started receiving texts from royal mail claiming to have visited my house to deliver the parcel but I was not home . That was a lie, for the whole of that month I was indoors being sick from work. Text requested for me to pay a small amount for the parcel to be delivered. I was desperate, my son was joining a new school and I wanted to be able to communicate with him. I paid a small amount using my card. This was a setup O2 hard exposed my details to the wrong courier service. People started using my details to apply for loan facilities. I was contacted by several companies informing me of what was happening. O2 caused me to be a fraud victim. Instead of accessing the services that I requested O2 concluded that I had updated my existing line, this was wrong, I kept calling them and talking to different customer service staff who give promises that never happen. I finally decided to move to another provider and was charged a penalty. O2 does not care about losing a small customer like me all they know is that they can threaten you by spoiling your credit score.O2 customers be careful 02 will make fraud victims. When I complained,I was told to wait for a manager to call me the following day. I am still waiting for the call.
