Telkom LTE Home Office pakage

I bought a Telkom LTE Home office 20GB per month contract from in November of last year. LTE is far better than ADSL and all has been going well. However, I have realised that the 20GB package is not sufficient and to top up data is extremely expensive (R999 for 10GB). I decided to move to the Home Office 50GB package as it makes far more sense for my monthly requirement. <br> I went to the Eastgate branch for what I thought would be a simple upgrade/ migration. To my absolute dismay, I was informed that the Telkom systems can't accomodate such a move (Amdocs). The only way for me to be able to move from 20GB per month to 50GB per month was for Telkom to cancel my 20GB package and then issue me with a new 50GB package. I spent close to two hours at the Eastgate branch and eventually walked out with new SIM cards and a 50GB package. <br> The new SIM cards don't work as they have not been activated. I have been back to the branch and have tried to get them activated but when they will be active is a mystery. Thank goodness the branch staff have been helpful but they have systems that are just not customer friendly. I now have no internet access and I work from home.Please help me.
