Telkom showing the middle finger

The most pathetic service from Telkom and Bonga Ngwane on a Saturday. I had to submit something very crucial at work…Telkom showed me the middle finger I need Telkom to refund my full premium for October. Telkom is ****ming people the most pathetic service. I asked for a manager no one budged to help . To make it worse my family members are experiencing the same thing, where can we properly report Telkom
