Upset is an understatement

Let’s start here, I have been a Rain customer for years. Unlimited Wi-Fi month to month subscription. Never underpaid never overpaid until now. Last month I updated my 569 subscription to 625. Upon date on upgrade I paid 40 odd Rands with a discount of 250 then on date of debit which was Feb 25 200 odd was deducted. I’m okay with this coz all of that kinda makes the new 625 subscription. So what should happen is that on the 1st of March my invoice should reflect 625. Woke up today with a 1400 +- debit order from Rain. I go online to see why? They have charged me 569 and 825. For what I cannot open my invoices to understand properly so I ask their AI this morning what’s happening, the AI admits that there is an error but further investigation can only be done by people so AI sends an email to them to call me back. 14 hours later nothing.

No company should just bill what they want and take what they want from the bank. Can Rain please just refund me my money. I am a single mother of two kids and have no time for this.
