Unfair customer service

BOSCH Diesel Electric in Bethlehem Free State Province, has no respect for their customers and have proven that ****** still exists. One of their employees Hannes is rude and lacks customer service, we bought a car battery less than 2 month back and the battery is dead. When we tried to return it we were met by Hannes' rude behavior where he told us he will not change the battery and he will not go into the system to check for the purchase because we are wasting his time. He then proceeded to treat us like we don't exist because a fellow white customer walked in. This service is very disgusting to say the least.
