Poor service being BS after doing upgrade

I app**** for an upgrade which I received, was dealing with Jessica at corporate or advised that the upgrade went through. I received my handset which was delivered by the couriers on Thursday, did the sim swop tje afternoon. The agent advised that the swop was done succesfully. Thursday night I was still unable to use my handset as it kept saying emergency calls, no network. But the joke is I was able to make calls and sms. The handsets camera colour is also out so the handset is also fked. I even put the sim into another handset and it gave me the same problem NO Network!!!! Friday I was on the phone since 8 am trying to sort out this problem going back and forth between 808 and 1555. And still I am sitting with the same fking problem. This morning I went to one of the franchisers in Strand who told me that the sim was never activated on the network...so I was **** to the whole day yesterday!!I am very ****ed off because now I can do nothing with this dud phone, as the courier can only fetch it monday then I have to wait 5 days before getting another handset!! This is my business phone and don't have anothr handset. So I'm sitting now without a phone!
