Poor online service overall poor service

Can i please ask that my latest purchase be canceled and my account be closed. I had enough of truworths who always slip up and to cover it up come with excuses... I purchased 2pairs of takkies before xmas and i knew it would not be delivered in time which i was fine with. So i received and SMS on the 28th stating i should be home between 8-5 on the 29/12 as the courier which i pay for to deliver my parcel which they failed to deliver on the 28/12 as they had my parcel in their possession since the 27/12. Parcel is not instore or at the wear house but in possession of the courier since the 27/12 and we going on day 3 and its still not delivered.(they not delivering my parcel for free lets get the facts right) so today whole day i had to wait for a parcel that was not delivered, no call to say it wont be delivered or anything.. i had to now guess they not coming... called the call centre just to hear a bunch of excuses and talks about SLA... when you commit to a delivery and create an expectation SLA is out of the door and if the service was free it would've been something else but i pay for a service that is not up to standard. If a courier service who gets paid to deliver parcels decides when to deliver their parcels after a commitment sms was sent i reckon you consider a reliable and truworthy service provider. In closing dont send the parcel we dont want it anymore and cancel everything and close my account. Poor service and i am disgusted with the fact that i had to follow up not one but twice... fool me once shame on you fool me twice shame on me. Dont call me with excuses and empty promises and this and that, just close my account and send me a notification.
