Ethical Business Maybe NOT Jenny Internet

Jenny internet has been charging me R600 more than what should be the normal cost and when asked why not the accounts, sales or support dep can not give an answer. I have been with out internet for a week and have logged a call every day, I was told I am disconnected and i need to pay the technician Daniel Ras R 750 and sent proof of payment before anything will be done. Thant would be after I am over charged with R600 every month and did not get the connection I had to pay for in advance. The other question Jenny cannot answer is why am I disconnected as I have paid for the month of June. I was informed by Jenny Support that I have been disconnected, that would mean it has to be a fault at Jenny Support, then why do I have to pay a callout fees to correct what Jenny did? Having said that I did agree to pay the callout as I could no longer be without internet and as of Friday until today Jenny had not called me back to confirm when Daniel Ras can make the time to come and re-connect me due to Jenney dis-connecting me. I was just wondering is the disconnection not done deliberately. I have on several occasions requested to speak to a senior person or a senior person to contact me .without any luck. Sam from Jenney support keep on promising he will contact Daniel Ras and confirm however not one of the two has contacted me today. I am just asking how is it ethical to charge a client for a package that does not exists and then clients must pay to be re-connected after Jenny for no reason di-connected them.
