Pick 'N Pay Ola supermarket

Today I went to get a cash back at Pick 'N Pay Ola supermarket in Bophelong 1045 Moraka Street yeei the whole staff is rude they won't even bother to give you half of the money you are requesting they will will tell you in a rude manner "we don't have money". They have no customer services at all we've been complaining to management but nothing has been done to improve the service
