Inconvenience to customer due to *********** staff

I recently ordered a Rain Data sim card from Rain, unfortunately my experience with them hasnt even started due to their inability to get my sim card to me. I placed the order on the 26 February and was advised that they will hand over deliver to the courier within 5 days. RAM sent an email yesterday 02 march informing me about delivery i then contacted them to advise look i work and i only get home at 4.30pm so they would have to deliver at that time which they said they are unable to do i need to then change the delivery address. I spoke to kagiso and she then noted to me that she would change the address to my work address and the delivery would then only happen the following day 03 march and that didnt happen because this morning i got an sms and email with still my home address.. I then called RAM again spoke to a lady by the name of yanga she said she would get back to me after checking everything and that also didnt happen. I called back and spoke to Phumi she advised that she could see on the system that i called twice to change the address but it was never done and if she changes it again the delivery would AGAIN be delayed to the following day. I am so not impressed with this ****. I then got a call from the courier person who was supposed to deliver my package he wanted me to know he is on his way i then asked him to what address he mentioned my home address, which means no one had even bothered to inform this guy im off his delivery route... I then explained what has been happening with regard to the address change and he then said okay the package will be delivered next week sometime and dropped the call... NEXT WEEK!!!! Bare in mind i have already paid for a service from Rain that i am unable to be using due to the incompetence of RAM couriers and then i decided to call back AGAIN to hear what the hell is going to happen now i spoke to a guy Lucas who placed me on silent and on hold for almost 10 mins... So why should a customer have to deal with this. Im in customer care and i dont treat people like this i would like to get feedback from this people as soon as possible because now again i dont even know when delivery will be happening cause no 1 is getting back to me.. IM THE ONE PHONING AFTER THEM AND THEY PLAYING A CAT AND MOUSE GAME ALL THE TIME.. Its not cheap calling a 086 number everytime for 10 to 15 mins everytime....
