Called a ****** by a manager

I took my battery to Battery Center at Vryheid for testing around 10am, the guy told me that its dead so he'll have to charge it first for him to be able to tell if it got a problem or not. He said I'll have to pay R20 for charging, which i agreed to.

I came back around 2pm to collect it, i was told that it's still dead i should come back later, i didn't have time so i wanted to take the battery and leave but i was told to pay.

When i refused to pay cos it was not charged some guy came along and said i should pay for his electricity and he took the battery away ''a manager i suppose''. I asked for his name and he said he's ''Lood'' or something, I told him to write it down, as he went for his pen he said ''******''

The argument ensued and he kept the battery as i didn't want to pay for it since it was not charged and they couldn't check it
