Worse internet service provider

Worse service provider they are (Webafrica) I joined their WiFi package and their sales consultant informed me that I pay it month end through out the time as long as I am with them. I received invoice email within a day from joining I email them enquiring about the invoice I received as I was informed differently. They did not reply to my email through out the day I decided to send them a follow up email the next day they also did not reply that was Friday on Monday when I came back from office they had suspended the line I emailed them again to try listen. To the conversation recording I had with the sales consultant regarding information he had given me about payment methods they still did not contact me I called then a lady who answered very rude and did not even try by any means listen to the conversation recorded as I requested she didn’t even bring a solution but kept telling me at Webafrica they set out billing payment methods and the fact that Webafrica sales consultant told me otherwise not same information as she was telling me she didn’t care to listen to that nor give someone a phone who can have a different view for us to reach a conclusion In my understanding they are worse at communication and cares nothing about client
