Terrible service

They came to deliver at my address without calling to inform me Friday 4/06/2020. Saturday I call the call center after trying the number that's on their website that doesn't go through. I got through to a lady that said she'll email the Durban branch and the delivery will be done by Tuesday. Tuesday no delivery. I call again. They put me through to a very rude lady from the Durban branch who dropped The call on me after taking my details and not telling me when I'd get my delivery or a call regarding the delivery of my item. Cotton on its self doesn't want to get involved. They just say they've emailed them. It's now the 11th of June. No parcel. I'm so frustrated and annoyed
