Telkom is a ****

I’m so disappointed in Telkom I have been a client with them since 2019 taking different contracts packages and I’ve recommended family and friends cause of the good service I use to receive over the years till this year, I had a cellphone contract with them so because I wanted to cut off on my expenses I called them requesting to cancel and to get a settlement amount I spoke to a lady she gave me a settlement amount and assured me that is all I need to pay, I then made the payment and I called in to find out if is there anything that I still need to pay they assured me that all is settled I was even sent an email that the account is successfully paid and I don’t owe anything but to my surprise last week when I got my statement it says I need to make a payment of 1800rand and when I called in enquiring about this no one seem to give me a proper explanation I’m so disappointed in Telkom when did you guys become ****mers, I regret the years I’ve spent with yall let alone all the referrals I’ve made to yall
