generic cartridges - extremely unprofessional

I ordered several ink cartridges online and paid at the same time and they were to be sent to my office in Durban. I received an email that they received the order and payment and they will keep me updated about the progress. And that was IT. 2 weeks later and having written several emails and made 3 phone calls - I still didnt have my cartridges nor is the owner/manager Gavin responding to me in any way or form. I finally get him on the phone (on a Friday) and he insists he was responding to me (which he clearly didnt) not via mail or phone, then he said there was a problem with supply on my cartridges, then he said it went out today so it should be with me Monday or Tuesday, then he said he made a mistake it actually went out the previous day and I should be receiving it today or latest Monday. All of that in one conversation. I also asked him to resend all those email he apparently sent, for after all - he somehow got it right when the confirmed the original order. Needless to say - I never got the emails up to today (another 7 days later) . Yet I also didnt get my delivery as he said yet instead I got a message from POSTNET that I need to fetch a parcel from them (across town) with no reference where from etc. When I managed to send someone there it turned out to be the ink cartridges that they sent to postnet of their choice instead of delivering it to my office as promised and needless to say not a word from them. Funny thing is - they were sent 3 days before I finally got Gavin on the phone which literally shows I was just told a whole lot of lies . Totally unacceptable, unprofessional and plain down disrespectful on every level. Never ever again , what a waste of time, money and resources.
