Unacceptable client services

How does discovery justify two increases a month a part ? How do they calculate there increases which are way above inflation? When I started with discovery at the end of the first year they gave me an increase of 21% . I sold the vehicle got another another vehicle now this year they giving me an increase on the 1st of March called the annual increase and I got a letter yesterday saying die to the economy and other stories I will get another increase . I called them today and nobody can tell me what the second increase will be . This is pathetic and beyond acceptable .
