Unexplained billing- no accountability

Telkom is charging me for services not received, and services not procured.

I have been in store, spoken to call center agents, I am currently on a chat and the person just stopped replying.

Please pull the call where the sales associate told me that I will only be billed from the time I receive my items. Instead:

1)The technician comes out without a router. I am billed for a service fee, which should have been void as I am a contract subscriber, not a month-for month customer.

2) I am billed a prorated fee for November, where my subscription was only active from the 13th as I had no router to access the internet from. I was expected to pay around 1800. The store workers told me, just pay it they will credit you. DO NOT TAKE MY MONEY when this is your mess up.

3)Now my bill sits at 1632.69...when this was supposed to be around 799.

As a former Telkom employee, I am so disgusted by the way you operate. Sort this out.
