Atrocious Service

On the 30th of August I called customer service to black list my phone as I lost it. I was told that they will send me itc number till today I haven't received their sms. The next day I went to Hi store in Maponya mall for a sim swap and I was told my dim card will be activated within 72 hours that didn't happen. On the 5th of September I went back to the store to inform them my number is not yet active we contacted customer service. Customer service requested for the store to resend the form completed and my sim card will be activated in the next 24 hrs that didn't happen. On the 9th of September I contacted customer service I was taken from pillar to post, then finally I was transferred to the correct department only to be told that my query has been logged on their side they will follow up. I was hoping that today my Sim card will be activated but still nothing has been done. Today is the 10th day without an actived Sim card.
