Telkom Sales Department dont care about their clients

Telkom sales department dnt care about their clients, especially after they have agreed or signed on the dotted line last Month August after refusing for a long period to upgrade, I upgraded my My router from 20-20gig R249pm to 40-20gig R350pm, this month I get a bill of R1000, I then consulted them for the explanation, Ayanda Thony from Telkom could not give me a clear explanation, she then suggested I call Billing department for an assisted Alexis Miller then said not in so many words the person who sold you the New device basically did not care about you, he maximized profit as much as he could, making me pay for two devices and including insurance without my authorization. I regret the day I spoke to Telkom sales department for an upgrade. the *** thing is they where calling at least 4 times a day offering their promotions on devices, now that I need their help they are turning their back on me

I am also trying to cancel the that insurance of which is stated on my statement Finrite, nobody can assist including Vall brach mall
