We do not owe any debts to anyone and our credit rating is superior. 

When Midland credit management calls there is no one on the line therefore, we can not stop the calls. 

Midland credit management has called XXXX times in the past week. 
They call before XXXX and after XXXX. They sometimes call every hour for extended amount of time. 

We have tried blocking their calls but, they just change numbers.
