Sim Swop

I've received my phone - new contract in December 2015 and after weeks they've done the sim swop, after<br> it gave several errors due to my address or whaterever, and they told me at the end it was referred to the IT department and it was a fault on their system. My phone worked perfectly until yesterday afternoon when it went of and said service disabled, emergency calls only. I've phoned in and Lesego Majafa tried to helped me and said the IT department said I must put my phone of for an hour and then it will work. After an hour it was still not working and I've spoke to Lesego again and he told me to go and buy a new micro sim. I did and tried to do a sim swop again and Resilwe helped me. Then another error came up and she must refer it to the IT department and now I have to wait another 24 hours!!! Come one, this is know the third time!!!! What is wrong with their systems and WHY are they not fixing it???? and why was my sim card work perfectly and suddenly went off??? Lesego told me that the sim swop was not done right on their HOR or whatever system and that is why it happened!! Come on people, no customer service!! and everytime I must use someone else's phone!!
