Matrix Cellular — fraud

Address: Pune, Maharashtra

Hello,My name is Ashish Khandewale. I am a student currently studying in london,uk.Before leaving India MATRIX cellular company's employee Mr.Ankit Agarwal called me to discuss about international simcards. I went to his office and he said I wil be having free calls in uk and free 100 mints to india. When I reached uk I found that I got charged for every call I made and got bill of rs 8000.. I called company and asked details,I found that I didn't have any free calls only for T mobile to T mobile.Matrix did not mention this when I bought sim card. I asked them to terminate my service as I used it only for 10 days. They said it is not possible I have to pay £160 as termination fee. As I am student I am not able to pay such huge amount. Then I talked with manager he said my guarantor should pay money. I said to them I was alone at the time of signing form so no one signed as guarantor. Matrix's employee Mr.Ankit Agarwal made a fake signature of my father as a guarantor and started mental agony by calling my parents for money and blackmailing every time by saying we will sue in court. As their employee made a fake signature of my guarantor how am I liable to pay?please help me
