ZERO for customer service. Confused service provider

I'm disappointed in the service that they have given me.

I upgraded my internet package from 5mbps to 10mbps at the beginning of March.

I was sent the invoice for the month of March on the 30th by Chantelle Wasser. I paid and sent proof of payment. After looking again I realised I had been charged for 5mbps and contacted Chantelle for a correction. She swiftly called me and said she forward the updated invoice with porata for the change.

Only later did I see the email, by then it was after business hours & I assumed I could rectify it on Tuesday when the Easter holiday was over. Today they cut me of. Easter Sunday. To add insult to injury they seem to have now charged me the remaining amount for March (understandable) but also the full amount for April.

The confusion in this organization has now strained what was going to be an enjoyable long weekend with my family. My family and I only use streaming and do not have a dstv subscription, so TV is no longer on the table. I run a small social media business which means I work in the internet and have no business hours in essence, I can't afford to take breaks during holidays or weekends, I'm now out of pocket for data in order to work.

This is unacceptable, they don't even have a 24/7 customer service for me to resolve although they have that stated on their website.
