Buy Faulty old Battery to be charged by Stafix (Campion 12v 9AH)

Stafix Bloemfontein not prepared to exchange a faulty battery. They insist that the fault is on the charging unit of the Centurion D5 gate motor. I have explained that I have tested the charging unit by placing a load over the unit and the unit function perfectly. In stead of replacing the battery they indicated to charge the battery and I must return in one hour. I have expected Beter service as the battery is still new and under warrant. Don’t buy from them no backup service and commitment to make customers happy.
