Account Query still not addressed two months later

I ordered my VOX line on 15 July 2015. I was immediately charged for a 10Mbps line and 100Gb data for 16 days (15 - 31 July 2015). I wanted 4Mbps from the start and called the call centre to ask if I could change and the message was that I could only change it once the order was processed. I accepted that.<br> <br> In the meantime, Telkom struggled over the next few days to get the line active and apparently the line was eventually active on 23 July. Telkom also noted from the start that they could never get a 10Mbps line and had to opt for a 4Mbps line instead. <br> <br> Issues:<br> 1.) I was charged from the 15th of July instead of the 23rd for the line rental. I am happy to pay for the data because that was correctly allocated to my account.<br> 2.) I was charged for a 10Mbps line instead of a 4Mbps line for July (16 days) and August (full month).<br> 3.) I was charged for 30 out of 31 days line rental for Sept as well at the start of August. I was charged for the Sept line rental again now (double charged there as well)<br> 4.) I had to call them 6 - 10 times and mailed 3 times already and it's still not corrected. <br> <br> I opted for Vox because of the good apparent client service, but all to no avail so far.
