Availibility of part and lack of customer service

Have been waiting for over a month after many phone calls and emails to receive resolution on a part no longer available for a Samsung vacuum cleaner which is only a few years old. Many promises to get back to me never fulfilled and their recommended service provider is even worse.<br> <br> Pretty pathetic if the customer service has this lack of service.<br> <br> There is a lack of accountability as it seems they know that nothing will be done by anyone and there is no escalation.
