The worst delivery service ever

I made an online purchase yest (clothes) and stupidly opted for delivery at home instead of shop as I ussually do since my last encounter with your courier,thought service has improved.I wrote specifically on the order Call when at the gate,ofwhich last time that was an issue,they just come and miraculously expected me to know that they are outside,mind you I live at an apartment.So today the guy decided You know what I ll send an sms,like really maar...I was supposed to have my eyes glued on the phone the whole morning so that I can see the sms of someone waiting at the gate.So after a while he decides to call and when I tried to answer he dropped,well i called him back immediately,he tells me he's been waiting outside and he left because I didnt respond to the sms message,he even had to go buy airtime,very rude that Moses of Fedex.I dont understand what is the problem with your courier guys calling...last time we had the same problem.I.make online purchase all the time,even from your other brand @home,made quite a few purchases @home,not a single problem with delivery never.I buy from zando,runaway sale,superbalist,takealot you are the only one with a problem to call when driver is outside or atleast when he is on his way to me,the only one.I am so upset right now I feel I dont want those things anymore the way Moses from Fedex was rude.
