CenturyLink Returned equipment and they are refusing to refund me Nationwide

Back in September I terminated my services.  I requested 2 shipping labels to ship back the 2 DSL modems I had.  Never received them.  Called back 2 weeks later and requested the shipping labels again.  Never received them.  On 10/28 I was charged 104.23 on my credit card.  Called them the same day and requested the shipping labels.  This time I received them.

According to UPS they received the 2 DSL modems on 11/08.  I just talked to them tonight and asked about the refund.  They are telling me they are not going to refund me since it was more than 30 days since I cancelled my service.  I told them to return the modems to me then.  They told me they can't do that either.

So I filed a dispute with my credit card company.  Lets see how it goes from here.  Funny thing is the lady at the credit card company told me she is going through the same thing with CenturyLink as well.

Can you say scammers?  Or is it really a case of really bad customer service?  Maybe the people working there just don't care.  Who knows.
