Apology on behalf of a person who had no clue

Id like to take this opportunity to apologies to JP from House of Ribs. I booked for an event and because of a the number of rsvp's I decided to call them on Wednesday 26 august 2015 to inform them that i was no longer hosting the event and would like to come and eat in to redeem the deposit. we went there on Saturday and redeemed the deposit without hassle. on Sunday i get a call from JP to say that i listed him on hello peter and it was not me. i phoned around to ask who would interfere in business that they dont belong to only to find out is a cousin. She is giving me a lame excuse that she had a bad experience when she called house of ribs of which i dont see it being any of my business. she logged an email with you guys on sunday 23 aug 2013 as per mail from JP. You are a good manager and dont let people take you otherwise. you were very helpful on the first day i come to you and even on saturday.
