  • Buyer beware! I have been a Calfo customer for a couple of years. Previous experiences were good but my latest was absolutely terrible. If you like scare tactics and being overcharged for repairs you don’t need, this is the company for you. I’ll be taking my business elsewhere and I’ll continue to tell all my friends about this latest disappointing experience with Calfo.
