Exceptionally Poor Customer Service and ********* Practices

If I could give them no stars, it would be too much! I have had the worst experience with Rain throughout my 12 months with them. Firstly, they have no working contact number, so if you have any technical issues, you are left to your own devices to try and resolve the issue and logging a ticket on their app is pointless as they will send an email with a reference number, but they don't ever actually respond. I have been paying R499 per month, but for the full 12 months, I probably only enjoyed an actual connection 70% of the time with zero to no technical support. It gets so bad that I am not even able to use my cell phone for WhatsApp while I am watching Netflix. Pathetic to say the least! Secondly, they deduct money from my bank account every month and for September, the payment was deducted twice. I logged a ticket (Again because there is no working telephone number) and they said it was because the previous month was unpaid. When I sent them proof that the account was indeed paid, the story changed and suddenly I get told they bill in arrears and therefore 2 payments were deducted. I have begged them to phone me, but I keep getting the same generic reply and no acknowledgement or feedback on my actual questions. I have submitted proof of payment 3 times and all they keep saying is the accounts are billed in arrears and the payment on 25 Aug was for July and the one on 2 Sep was for August, but every month prior to that, they have always only deducted money once on the 25th or 26th of the month, so what makes this month different? I have also cancelled my service with them and suddenly out of nowhere I get an email saying that they have upgraded my streaming experience to make signal better! Why now? Why when I cancel and beg them for 12 months to sort out the signal, do they suddenly do something to assist? Please DO NOT fall into the same trap as I did and use these people for your internet needs. They will give you ****ty service which they will only attend to after you have cancelled and then deduct money without your permission and not give you feedback or bother to pick up a phone to call you back after begging them to do so. They are VERY quick to call and harass you to make a sale and then they disappear! To say I am angry and disappointed would be an understatement. Run as far away from Rain as you can get!
