Sorry but not sorry enough to refund you

Woolworths accounts for 95% of my monthly grocery spend. In January I purchased a watermelon which turned out was spoiled and totally unusable. I logged a complaint expecting a quick refund. Instead I got conflicting messages and emails claiming they tried to call me without any missed calls. After two weeks I got a sarcastic email saying they cannot cut open every watermelon to check if they off- so sorry, hope you understand. That’s R110 thrown away because Woolworths won’t refund a loyal client for a spoiled product.
