I want my money back

Im tired of this people is like they dnt know that I'm working and at work we are not allowed to answer phones because we are driving. They will say there called twist just to make themselves look good . I have been waiting for them to call again but no please help because they know that there is a case that is not finished but they dnt follow up on it to complete it . The customer service sucks and they dnt care about there are customers
