tried to call on land line goes to the number you are calling is switch off or unavailable

Tried to call this number back. It went straight to hold music. When I listened to the message they left it was clearly a call centre of some sort (they didn't leave a message but I could hear a lady speaking with a strong Indian accent).

tried to call on landline goes to hold music playing so i guess its another unwanted call wanting to sell you something ** go away * not interested and how is it that i am on the do not call list >>>>>>not happy jane
