non-delivery, inaccurate info & refusing to cancel

My parcel (valentines) was supposed to be delivered on 11-Feb. Unfortunately the last line of address was wrong. I was notified 15:00 on 11-Feb (non-delivery). I immediately phoned to correct. Warren phoned back at 15:30 & confirmed that will be delivered morning 12-Feb. 08:15 on 12-Feb call centre confirmed that parcel is on truck & will be delivered soon. 10:00 call centre confirmed that parcel is out for delivery. 12:30 call centre said that parcel has not been allocated to driver yet! Would only be allocated at 13:00 (delivery 13:00-17:00). I asked operator to cancel order as my husband would not be available from 15:00 on 12-Feb. On 13-Feb 12:30 I got a non-delivery email. At 14:00 13-Feb operator phoned my husband to check if they can deliver - spoiling the surprise and AFTER I HAD ALREADY ASKED THEM TO CANCEL THE ORDER! Again asked operator to cancel order. On 13-Feb 18:00 I got an email from Nico Khoza stating that driver received address late & asked if parcel can be delivered on 16-Feb! I again requested cancellation. If you do not have capacity to deliver, then I should be notified on the day. If I say cancel my order, then ensure that my order is cancelled & refunded
