Woolworth, not a good experience

My 70 year old Mother made an account payment of R1000 to WW Westville on 05/04/2019 at 12:38, and made a purchase on the same day. However WW have no record of the payment or the purchase. The store stated that no payment or purchase has been made. Bank statements of the payment have been provided, numerous telephone calls later, and still no response. This morning an extremely rude lady in the collections department put the phone down on my Mother. To top it off every day my Mother receives calls from WW collections department demanding payment! Very poor customer service. I wouldn't recommend opening an account at WW.
