Senior citizen Discount

     I'm a Senior citizen and have internet only. I complained about the cost increase and wanted to drop cox. She in returned lower my a bill a little  but not as much as it was.  She said I could go to one of the Cox stores in my area and show them proof of age to get a Senior citizen  Discount which would be another 7 dollars off .  Today I went to the cox new Orleans store  and they said there is no such thing as a Senior citizen  Discount for internet.  Was I lied to ? If not how can I get that  7 dollar senior citizens discount?
