Refusing to pay for their *****

We cancelled the a possible sale with TATA Pretoria North after the vehicle was not in the condition one should hope from a dealership. We didn't sign any documents to have the bakkie put on our name. Then after a while we realised that the bakkie was suddenly put on our name by someone signing the documents in my name. The person driving that bakkie then went through all possible etoll gantries and all expenses ended up on my account / name. Now TATA refuse to pay those etoll accounts. I've send numerous emails to TATA, I even send a complaint to their head office. Nobody wants to take responsibility for this and now it is my problem to pay the etoll account for someone else due to the ***** of TATA. This is ridiculous!!!!!
