what are my rights in a case in which do i have a right to sue? i signed a contract with a tax consultant firm to represent me at an irs exam. they failed to represent me thus leading to me having to cancel service with them and represent myself. they charged my credit card a total of $4800 but did no service. i have proof that they were not there at the exams - it took 3 exams but i was finally able to get out of the mess in which they only mad matters worse. now they will not return my phone calls, emails, or even my certified letter asking to be refunded my money. do i have a right to sue them for breach of contract?
