Worst customer service at Woolworth Cedar Square

I have shopped at Woolworth for many years, especially during pandemic which i find its online shopping platform very user friendly until today. They insisted of dumping 1000 packs of biltong and dry fruits at my premises which i told them they must have made a mistake but they showed me their delivery note indicating my address with the goods to be delivered. Luckily I was home today. After few hours, they called me saying that they made a mistake and they are coming back to collect their stock. I was extremely frustrated with the stock taking up my living room space and it is during pandemic with water outage in my area that i could not wash my hands properly and sanitize their stock. I requested of speaking with their supervisor or above to resolve the issue, but they kept sending the driver the delivery guy to come and collect the stock without communicating with me. None of them could give me a satisfatory resolution and one threathening me of closing my Woolworth account. the worst is the woolworth stock manager- Gavin at Cedar Square saying im *********ing him and he will call the police. When I asked him to go ahead with it he backed down but told me that I was wasting his time and I am *****ing his 80k worth of stock. He eventually agreed to compensate me with a R300 voucher which was never delivered. He shouted at me while i was opening door for the stranger (delivery guy) to come into my house to collect their stock. I am extremely upset and frustrated with their attitude and they have the audacity to tell me that i am also at fault for accepting the goods. what kind of customer service is this for a force delivery and later on complained about the customer for accepting the goods. It is the worst of the worst! I cannot believe Woolworth with such a big corporate claiming to have the best customer service to be so cheap and treat customer like ****s! Woolworth needs to train their stuff, especially manager properly to know how to communicate with the customer, the driver told my **** that they often deliver the wrong stuff to the wrong people. Woolworth needs to fire this Gavin/Gary guy instantly!
