|I think your tale is quite funny. It is the grammar and punctuation that are not quite spot on although some might be typos. First line phone or phones? Second line 2500 office(s).Missing speech mark after mind.
Third paragraph try:
"His name is Dee, right," my husband said.
"No, his name is Cesar."
"No, he answered the phone with his first name, his last name is Cesar," my husband said.(argued/insisted)
"No, his first name is Cesar, his last name is Salazar," I replied.
Each speech should start a fresh line to show a different speaker. And try using alternatives to said.
