I am being harrassed by calls from shaw's telephone number [1-888-444-5308].

The voice mail they repeatedly leave, only minutes apart, claim they will shut down my service in two days due to non payment of bills [false]. 

I always pay online, and have printed verification receipts for all. 

If this really is Shaw, then you have just lost a customer. 

If it is a scam, tell me how to end it.
