Billing Issue

I received a bill of R1102.66 for the period of 20 July 2018 - 09 September 2018. This bill is incorrect. I only had the ADSL line installed on the 28 July 2018 and was only able to access the internet from that date. Also there has been 8 days I was without internet and have logged this with the technical team. I spoke to someone on the 28 August 2018, who wasn't very helpful. She logged this for me and told me someone will contact me in the next 7-14 business days to discuss compensation and if I do not make the full payment 15 days after the payment due date which is the 31 August 2018 my wifi will be suspended and I will need to pay R260 odd to have it reconnected. Why must I pay a bill that is incorrect? Telkom is billing me for a week before I had the ADSL installed and I was from the 02 August 2018 - 10 August 2018 without internet yet I must pay for that time I did not have access to the internet. The bill needs to be compensated for the total of 16 days before I make payment because the fault is from Telkom's side. Making payment is not the issue. I just want to pay for the days I am liable for not what Telkom is assuming I should pay for. Your call center agents are a bunch of *********** idiots who makes up BS stories all the time and has absolutely no telephone etiquette. I want this matter to be resolved ASAP so that I can pay my bill. I do not want to make the full payment of R1102.66 and then Telkom ends up not compensating me as they should. Also, I am now again without internet since Tuesday morning. I know this is due to cable theft but am I going to be compensated for this as well? I only used the internet for a total of 22 days so far out of the period you are billing me for and this is just the beginning of my contract. The service is ridiculous.
