Lens causing error message 01

Hello,

My Son has a Canon Rebel T7i, so I bought him a Sigma 10-20 lens. As he is using it, he gets a error message saying that the lens is not making contact with lens and to clean the contacts. He cleaned them, but still gets the error message. What else can he do? Should I send the lens back? Could it be a faulty lens mount? Your help is appreciated.

Regards,

Terry
