hUnH? .... In the world today, everything is available on the internet. I've got an advice. Stop paying people for stuff like this. If you want to improve your accent, there are billions of ways out there. Google.com, Youtube.com, Dictionary.com or even anything you need to know just type it and write .COM after it . It may lead you to what you want. Keep google n YOU TUBE your best friend. In my opinion, Search videos on Youtube, typing How to improve your English accent or how to develop British accent. watch British Movies. If you have interest, watch BBC as maximum you can. Trust me it will help you as it helped me out!
