POOR upgrading and feedback from call center

I was due for an upgrade Dec2014,not having any trouble regarding billing/services for 2 years the natural instinct was to stay with 8ta.My contract that was due for the upgrade was a Samsung laptop + 10 GIG data deal for R398 pm.I went to the N1 City branch in Cape Town where I made the decision to upgrade to a 10 day + 10 night-GIG for R199. There was some technical issue where they could not do the upgrade in store, the person helping me at the time phone their call center to assist where they advised her to log a ticket to report the error.I had to go back to the sore 1 week later as no one had given any feedback, they asked me to come back as the issue was still not resolved. After going back they advised me to do a telephonic upgrade, this was January 2015. Eventually in Feb a call center agent called me to say this deal was approved the first payment will go off @ month end. After 2 month we realized we only got 10GIG, after reporting this week by week a case was opened. I followed up with 8ta a couple of days later, case closed still no resolution to the problem, another case was open and I'm still waiting on feedback. 6 months later of paying for a service not given POOR!!
