Lindi should not be working customers, very rude

10 minutes ago I called home choice call center @***, because home choice has billed me for goods I don't have, Lindi attended my call , she was very very rude tome, something normal with black agents at home choice, when they talk to us its like we stupid who don't know nothing. the statement I received is dated 08.12.2015 for goods I returned on the 05.12.2015 and the other goods were never collected from the post office, why are they billing me, this even shows on my credit record, I asked Lindi to refer me to her manager, she never did, instead I waited for 10 minutes on the line until I gave up , the fact is there is many Lindi's at home choice and home choice is doing nothing about it,. please sort this out before I take you to court.
