If you do not receive a satisfactory response from customer service, ask to speak to a supervisor or manager at a higher level. Sometimes company management has more authority and resources to handle difficult situations. Investigate the laws and regulations that protect consumer rights in your country or region. If the company does not follow these rules, you can contact the appropriate consumer protection organization for help. In general, if a particular company has a huge problem with customer support outsourcing, it is likely that this company needs to get another support team involved and check how things will go with the new support team.
