Is this normal? If not, how can I change this?!
I've seen this issue occur on the forums and it's usually something specific to your phone number. Basically something wrong with the local phone company partners that are being used.
Your best bet is to track the calls (time and number calling) and get in touch with Tech Support (they may have to escalate it to someone who can check it out). But they may be able to track down the issue with their partner and get them to straighten it out.
If that doesn't work, a change in phone number may work. Did you port your number over, or is it a new one that you don't mind changing?

COntact customer support, and they should be able to take care of it, it is a known issues that occasionally happens, and since it is known it should be easy to get resolved. But you have to call customer support and stay ontop of them.
