Johnny Carino's review: not accepting a coupon

I called the Johnny Carino's in El Centro, CA to place a takeout order on 1-25-19. There was a coupon in our local newspaper for a buy one get one free entree, in the fine print the stipulations stated that the coupon could not be used for delivery. There was nothing stated in the coupon that says the coupon could not be used for carry-out. I was told that the coupon is not valid for curbside carryout. I tried to argue the fact that the coupon states:
"May not be combined with family night mondays, daily specials or any other discount/offers. limit 1 per table, no cash value, excludes taxes and gratuity not valid for deliver orders not valid on valentines day."
Nothing says that I can't use the coupon for a takeout/togo order. So disappointed with the staff and establishment. I believe that this is totally ridiculous that they will not honor a coupon! I would greatly appreciate a response to this complaint!
Sincerely disappointed,
Lori Chirico
