*****ulent contract in my name

Cell opened a contract in my name without my consent or signature. I have been calling for months to get help but no one can help me. They keep debiting my account, I reversed the debit orders and now it has affected my credit score. I did everything i was requested to do: police station avidavid, ID copy, but I have not been contacted to be given full details of my case. I have to contact them and when I do they send me from post to pillar. This has impacted my life so much because now I lost money and my credit score is affected. I don't know if I need a lawyer or what.
