Billing

I was due for an upgrade, I took a tablet beginning of June and opened another line. All of a sudden my bill is high. I called the call centre for explanation and told me that I upgraded before time so I will pay a certain amount for 3 months. I wasn't told that the time I took the tablet. The lady who was assisting me told me that I will only pay R170 laptop in June plus 2 tablets and my phone line. Please fix this and bring back my money.<br> <br>
