Henberg Vaalpark

One week ago I went to Henberg Vaalpark to get a HD PVR power supply. The woman told me they don't exchange them, but it is R200.00 for a new one. I decided to go and look if I cant get it cheaper somewhere else. Pick n Pay was R400.00 and Diamond Corner was also R200.00 so I decided to go back to Henberg, as they are credible dealers for Multichoice. When I arrived there yesterday to buy a R200.00 power supply, the woman informed me (with an attitude that there's something wrong with me, I did not hear her right) that they are R260.00 each, and she never said they were R200.00. After a huge argument I left the store and phoned Multichoice to find out what the going rate is for a HD PVR power supply. Guess what Multichoice said, and their calls are recorded, They are R150.00 each. So why would Henberg charge almost double the amount??????? Henberg will NEVER see me again, and neither will I EVER refer someone to them EVER again.
