Sales consultant who cares about sales and harming clients

I have been using Telkom since 2019 but Yho! I am very disappointed and very angry because they are ruining my credit and also my reputation with the bank because I had a fibre contract which I took out in 01/2023 and it ended March 2024 and I kept the contract on a month to month. I contacted telkom in May and spoke to a lady named Julie for a change from Telkom R654.99 to a openserve R409 of which she told me the application was a migration and I do not need to cancel as she will do it from her side. Now I am learning that she did a new sale as all sales consultants are hungry for sales and do mot care about the client. Now I am being charged for things I do not know because they keep on debiting my account and the funds are being reversed because I dont have the money to pay for a service I do mot use. I was only informed at the end of July when I enquired that she did a new sale out of desperation and now I am the one suffering. I so will advice people not to engage with this company as they do not care about their clients. They hire ****** like Julie. And when you call the contact centre they send you from pilar to post for a long time without being assisted. One person even said to me she will send me an email the following day on the 21st of August and till today I am still waiting and I am receiving invoices with additional fees. ***
