WHY MUST IT TAKE SO LONG AND HAVE SO MANY EXCUSES

My colleague ordered an upgrade on her phone from VODACOM. They promised to deliver it on Tuesday (never arrived), promised again to deliver on Wednesday (nothing), promised again to deliver on Thursday. They contacted her to say they were running late and would be there at five. She waited until 17h10 and guess what..... no delivery!!!. Tracking says could not locate address even though they have contacted her to confirm address. Called them this morning said they would deliver at 14h00. Told Pretty at the call centre that is not acceptable and want it delivered by 10h15 or I would post complaint and here I am at 11:35 and my colleague still has no phone. VODACOM YOU NEED TO LOOK AT NEW COURIERS. THESE GUYS DON'T UNDERSTAND SERVICE.....
