FASTWAY CAPE TOWN DON'T CARE ATTITUDE WITH MY DELIVER TO A WRONG ADDRESS

I placed an online order four days ago, and the delivery courier, Fastway Cape Town, notified me yesterday that "YOUR PARCEL HAS BEEN DELIVERED." However, no parcel was delivered to me, instead, it was sent to my OLD address due to a mistake from the sender, Funky Tights Pants. Upon realizing this, I immediately contacted the courier company to locate my parcel, as I never signed for or received my purchased order. The customer service representative at Fastway explained that it's not their responsibility if the sender provides the wrong address, which left me puzzled. I inquired about their processes to ensure correct deliveries and why they didn't attempt to contact me. I also questioned how they could assume the person who signed for the parcel was the intended recipient of the online order. Despite my concerns, the representative insisted that I resolve the issue with the sender. I requested the driver's contact details, but the driver failed to answer my calls or return them. I lodged a complaint with Fastway but have not receive a response or apology from them. Despite paying for delivery costs, I now have to arrange to collect my order from my old address. It's disheartening to encounter such a lack of customer care or effort to ensure customer satisfaction from businesses in South Africa. I feel frustrated by the numerous calls and emails, only to be ignored and passed from one party to another without any resolution.
