Woolworth poor customer service

The worst customer relations ever. I have ordered clothing from them online. The invoice stated that no delivery will take place on a Saturday and Sunday. They then tried to do the delivery on a Sunday instead of the Monday. Since then I have called then numerous times to find out when the delivery will take place but nobody can tell me when. I was told they tries to contact me on Wednesday and tried to do the delivery which is totally untrue as I was at home the whole day and can proof via my call log and video footage that this is not the case. I have called them again and was told on four different occasions that they will call me back, up to now no interaction from their side. I was told stories of delivery companies and delays due to flights and more excuse and no being able to contact their warehouse telephonically. The result is still don't have my parcel I ordered 2 week ago and no one can tell me how to resolve the issue
