Unprofessional service

Still awaiting delivery on an item which was meant to be delivered on 10 April, as per an email (although an sms was sent that delivery would be a day earlier, on the 9th). I have spoken to numerous customer care representatives, the term "customer care" being used very loosely. Each assured me that delivery would take place on the day that I called in; each also assured me that they would be following up with their external courier and keep in touch with me thereafter. At one stage, I was even put on a conference call with Skynet (apparently, issues with their delivery partner suddenly become your problem as a paying customer). It appears that the modus operandi is for no individual support staff to actually follow through on a delivery issue – instead, the customer has to log a new call/request each day. If you receive a response, you are lucky. My request to stipulate an actual delivery date and time has been repeatedly ignored or not adhered to. It is absolutely pathetic service.
