Wrongly charged

Web Africa is a ****mer they switched off my WiFi for 4 days and I informed them but no one helped me till I wrote the CEO an email on the 4th day Mr Seam Nourse . A guy called saying he saw the email what’s happening I told him that my activation had been off and everyone is not helping . He helped me activation then said there’s a bill which is wrong he will wave it cause who ever did this made a sale on my acc but I’m already an existing customer . Today I get a notification I owed R2000 I don’t know for what cause I never made a sale and clearly he did not fix it . I am so angry Web Africa is so negligent and they mess with peoples mental health. They are ****mers . Not I wrote the CEO he hadn’t responded and the agents on WhatsApp are saying they can’t help
