I called the number and got a person immediately. They are from Rev Cda calling about outstanding debt. I told them this was a new number I had only had for a week and he said he would update the file on the person they are trying to get hold of and that I wouldn't get any more calls from them.
They are "Revenue services of BC student loan"
But! They are NOT "bc Student loan"
they are a collection agency who now own your loan. They are also NOT Revenue Canada.
