I have a bill with Qwest Communications taht I have disputed with Qwest Certified mail RRR and I have the reeipt. They sent it to a CA and I sent the CA a Cease All Contact and Dispute Letter Certified Mail RRR. The CA refused to accept the letter and the Post Office returned it to me unopened. Meanwhile the CA calls every other day demanding payment and telling me they have no record of a dispute (I wonder why....).
Ok, now what? Do I just sue them every time they call me? I have notes of every call made after I sent the Cease All Contact letter that they refused.
