Service SUCKS and empty promises!!!

I received a call from my service provider MTN that im due for a upgrade which i gladly accepted and processed telephonically with the sales consultant, he then promised that my cell phone would be in CPT in 1-2 weeks to my surprise i found out that the cell phone was delivered to JHB by DSV mounties courier. I had to follow up where my cell phone was after holding for 50 minutes, a lady by the name of Rivonia advised that my cell phone had to reach CPT the 5 September already, she then promised to escalate it and call me back at 15:00pm,13th september as she would direct it to CPT so that i could take delivery the next day- Still awaiting her call and no delivery (NOT A SURPRISE AT ALL), the 14th i followed up myself and spoke to another gentlemen by the name of Leboga who then transfered me to Rivonia as he advised that the phone is still in JHB, she then promised again that she would get my phone delivered urgently but once again a LIE just to shut me up and get me off the phone line. I then called in the 15th to follow up AGAIN and spoke to a Lady Masidiso who confirmed telephonically that the cellphone is in CPT but the cannot get hold of me , when i asked what number they using she mentioned my landline which is obvious that i cannot trace missed calls from, once again another lie as my parents are home all day and no calls was received. I then asked her for the CPT DSV number which she refuse to provide me with, i then googled the number and called the office myself and then spoke to Renier who also promised that he would call me back with feedback as my cell phone is still not in CPT which MASIDISO clearly **** just to gst me off the phone as well as she obviously see my comments on the system and did not want to assist me!!!! Im highly upset as i have been **** to by staff of a major courier company and if this is the way the staff is being trained to sort out queries or trying to assist clients then they might as well shut there doors. MTN my cell phone provider is defnitely using the wrong courier service as this is a service break down and a huge disgrace! I will never refer this courier company to anyone may it be family overseas or friends as there service SUCKS!!! This is a Birthday gift to my sister and I had nothing to give her on her birthday this weekend due to your LIES and lack of service!!!
