I purchased a certificate for their $ 649 Roofing checkup. I have attempted to connect with Delphina Enterprises via their website, via emai, by calling their direct line, and via their emergency number. I have tried over several times in the past 4 weeks. They do not respond. Perhaps they Delphina Enterprises is no longer in business. I post this reluctantly but want to caution others from doing business with Delphina.
