Bad service

I have been trying to make payment for my webafrica account for the last 3 days and for some reason I am not able to because their agents are all telling me a different story. I just want to pay my account online but the one is telling me that I have no payment method and the more I am telling them that I don't have the option to add new payment method, the more they are telling me that I have a manual payment option on my account which I don't have. I need my wifi for work and their communication is atrocious. I would never recommend them, you wait 2 or 3 hours for them to respond on whatsapp and their response times when an agent does get to you is 20 minutes long
