Ongoing investigation

Someone used my name and ID and opened an account with Avon Justine and I picked this up on my transunion report last year 9 November. I phoned Avon Justine and the courier services had not delivered the products to the lady that pretended to be me. I requested for Avon to stop the delivery and I was told they were going to do so but they never did or get back to me. To this day I have wasted my airtime calling and no one helps me. I need my credit record to be cleared and they keep saying they are investigating and will give me feedback asap. It's almost 11 months now and not a single person from Avon has contacted me. They refused to give me the number and address used for me to do my own investigation. This is really upsetting
