This number is Appco Group Australia. They look after donation companies like 'canteen' etc.
Usually calling to welcome and thank for donation subscription or find out why you are cancelling.

constant calls and no one there

Thanks Jade, Yes it is Appco calling to welcome and say thankyou for supporting Canteen - the people who get no government money. They are the group who make life a little better for young people with Cancer. They give them holidays and fun times. These young people can do with all the help they can get. I am happy to answer their calls.
