POOR TREATMENT OF CUSTOMERS..No after sales service

Went in to return xmas gift at gateway branch.Had original price and shoes were in original condition .It was a gift so no receipt ..R450..Customer service Vanessa was not helpful told me to call customer call centre.I then requested to speak to store manager who called up the customer centre manager.Why was I being given the run around when the manager was in the store?Spent 45 minutes waiting for assistance.This was a gift.In it's original condition.Was not looking for a refund but merely an voucher as size was incorrect.Poor service by Vanessa who kept rolling her eyes.Left the gateway store with no resolution.Have been customers of Woolworth for over a decade now ..will need to re evaluate this.
