Worsed service provider ever

I had the worsed experience today with Telkom I even regret taking a contract with them. First I app**** for a cellphone contract online for Huawei mate 20 lite for 399 and it was approved, I was told before I get my cell phone they will debit R399 cool I they debited 399 on the 18th of January, last week I got an invoice stating they will debit R732 on the 25th of Feb and I called asking about the 399 they debited why is not substrected and I was told by Telkom the 399 that was a test debit and is not reflecting from the billing department and I asked why and they logged a call which is ********** 2 on Tuesday 12th Feb and they advised it will take 72 hours for the issue to be resolved is been over a week today I decided to call and I was told the money is not reflecting still what do you call that this 399 was debited over a month ago meaning my first debit for a 399 contract is R1132 what is that Telkom is ******** people and this is the worsed service ever
