Adam heard his  phone but wasn't able to react immediately because of the work he was doing. He did his best though to reply the call as soon as possible and when he got it he recognized the voice. "Hey there Sam. I have indeed tried to contact you earlier but you weren't available. I have received one of your flyers and wanted to set a date for an appointment. I can't handle everything by myself but I do want my place to be clean and I wanted to listen to what you had to offer."
