Being told that the wrong item is on the stcok shelve

I went into Cash build Kokstad to purchase two kitchen sinks . On the shelve where I two weeks ago purchased two kitchen sinks for R 382. 34 ,took the two kitchen again and got to the cashier to be told that they are R 1054.00. I went back with one of the workers to verify how this could be? Only to be told that the wrong items where placed on the wrong pricing schedule. New building but same old terrible service. Service stinks .Shareholders will not gain returns on their money invested and I for one can assure you on that. A mistake was made and verified ,recorded with pictures taken . If that is not good enough for bad service ...........you join the dots.
