I think they're running a **** operation

I think I'm being ****med by Rain. Originally had an outstanding bill of R1,587 (as according to their home page since being disconnected in February 2023 until present - I have the screen grab to confirm this). Today, I logged on to my account to settle this amount - come to find that that bill has been bumped up to R2,110. Okay??? (Maybe it's their safety machenism to have me one month ahead in my payments???) I call in to the Sales and Accounts department to make a payment arrangement, where I'd pay partially today and settle the rest of the outstanding amount by the 15th of the following month (15 May 2023). Which they agreed to. I'm then told that the minimum amount I could pay, was half of that amount; which according to the sales consultant would mean R1,058 (this was then confirmed by the "support consultant" where I was transferred to, in order to complete the transaction. Another red flag, the first being - I was asked to hang up, and that she would call me back. I guess the sales and accounts department no longer handles the billing, instead it's the support department now? Okay). Went ahead with the process, was debited the R1,058 and got reconnected for the next few 30-min before being disconnected again. Called in again; this time to the support department, since this is a connection issue not a billing issue. Where I spoke to heavily accent Indian agent (I'm assuming that's their international call center), who told me that he'd log the issue and forward it to the relevant department and then reconnect me. That didn't happen. Called in again to accounts department just to confirm, got transferred to someone else by an agent who said he's working with Cell C accounts. Where I spoke to a very apologetic "SUPPORT" agent, who told me that I have to pay an additional R1580 (remember, this is the original amount that I actually owed, before being told I owed R2,110) by the 25th of this month (April 2023) else I'd be disconnected. Instead of the remaining balance of R1058 which was originally agreed on, to be settled the following month. BTW: Each of these agents (excluding the international agent) told me to hang up the call, and that they'd call me back before I could finish the transaction. The last agent didn't mention the R1587 during the first call; she told me to hang up cause she wanted to confirm it with "someone" first. They won't reply to emails either.
