Disgusting Telkom

I have now tried everything I can to have my Telkom invoice credited and to have the incorrect rental charges corrected, but to no avail. Last month I was credited R1300 in disputes and was promised by your billing department that I would not have the same problem this month, but to no surprise I was again charged the incorrect amount. I have registered several disputes and was promised by your social media team that billing recommendations was made on my account, but it's all lies. Please sort out this mess due to your *********** staff asap
