Worst service

Ordered an item on a Saturday in Makro online and realized I ordered the incorrect item. Immediately called the call Centre, and they assured me the order was cancelled. Called again on Monday, it was not cancelled so the next assistant assured me it would now be cancelled and I would get an email at the end of the day, Monday 15:30 and I receive an email that the item is dispatched!!!!! I called again, made to wait almost 15 minutes to be told that it’s not cancelled. I then asked for it to be cancelled to then be put on hold for another 15 minutes. Phoned again and spoke to Sihle, who assured me the item is not dispatched and would be cancelled. I have still not received an email confirmation!
