Terrible service provider

I messaged on the 30 July to advise I'm moving homes, on the 31st July I messaged to ask if they can cancel the move as I am no longer moving. They cancel my invoice for R659 instead of the moving home invoice of R999. 1st of August webAfrica suspends my line, I was unable to make a manual payment because of incorrect billing, I followed up on the 1st, 2nd and 3rd of Aug asking for this to be resolved, agents were unable to assist. Mind you all this time I'm without internet. 4th of August I cancel my request with the billing department advising they will collect my router on the 11th of August, just to find out WebAfrica wants me to pay for internet for August and September even though I have NO INTERNET since JULY. I have spoken to over 20 agents and NO ONE can help me.
