Keeping Clients Hostage

I'm trying to release my line with Webafrica. I've tried to resolve the matter with the WHATSAPP group but the agents refuse to assist me once I ask them to release my fibre line. they transfer me from agent to agent and are very unprofessional.

I sign up with Mitchell's Fibre (Prepaid internet Services) you pay for the month you use the services. My reason for releasing my line is, I pay for a 40mgbs but I get slow internet. Now they want me the pay a R539 to cancel the line. NON of the other ISP asked for a release fee on the Mitchell's Fibre platform (VUMA FIBRE).

Webafrica agents refuses to assist clients that want to leave and keeping me hostage by NOT releasing the line. #RELEASEmyLINE Vuma-Fibre you urgently needs to look into this matter, Webafrica is keep your Fibre line users clients hostage
