Upgrading of my

I app**** for upgrading of electricity at Eskom in Modjadjiskloof. This was in January 2015. My meter number is ***. To date, nothing has been done. I have paid the upgrading fee in full. I have been liaising with Baatseba at Tzaneen Eskom. She told me the last time I spoke to her that she received a report confirming that electricity has been upgraded at my house at ga-Mamaila village, Stand number I12. I told her that it has not been done and she has been promising to check and come back to me but she never calls. For the rest of this week, her number ***) goes straight to voicemail. I am very disappointed and angry with Eskom's service. Am thinking of demanding my money back.
