Best Caulking Replacement in Phoenix AZ

Same problem with the last reviewer. They have serviced my pool for 5 years, and never was green until the last several months. It’s been green several times now and I’m ready to cancel. They can’t handle it. Also, I gave them a new card to charge me and they told me they added it to their system. Then I realized I had several months of unpaid fines from them, called them and they blamed it on their new “system”
