Bad service

I purchased a Nike sneaker and the sneaker had to be returned because of size. Nike uses aramex for deliveries and returns. I followed the return procedure on the Nike app that generated a return sticker for me for the shoes to be picked up. This pick up was scheduled for the 25 October 2024. The day came and passed and the pick up was not done. I called aramex and was told I need to give it at least 3 working days for pick up because of my area and that pick ups are done once a week in Bloemfontein. I became patient and waited. Still no pick up. It is now the 5th of November and I'm being taken from pillar to post with this pick up and no o e is helping. Worse when I call to speak to Thozama Madi ane whose supposed to be dealing with Nike deliveries and returns, I'm no longer getting response. It's either she's not available or if she is her phone just rings. I've been calling from yesterday and was told she'll get back to me but nothing. I'm sitting with shoes that's holding my money at Nike because of aramex. I'm so frustrated.
