Poor service/ no internet

I made a payment earlier today, and I still don’t have internet. I have sent proof of payment to the lady who assisted me when I needed an installation, sent WhatsApp messages but they r soo slow, iv been waiting for a consultant. I even sent an email and still no luck. Worse I didn’t even know the prices were going up, the last time I made a payment itwas 298 but now it’s 500. I am so disappointed, my assignments are due and I don’t have the internet
