Pathetic service from woolworths

I have received such pathetic service from Woolworths. On the 31st December 2020 i placed an order for a cake for delivery on 8th Jan 2021. The cake did not arrive. I called on 9th Jan and was promised a refund. I have not received my refund despite emailing many times. There is no response to my email. I tried calling the helpline and they are experiencing high call volumes. I will have to spend R400 in airtime to get a R300 refund. Woolworth truly terrible service
