Appaling Customer Service

Il start by saying the internet itself is pretty good, but when it comes to customer support forget it. I would rate Telkom support higher than Rain. They NEVER respond to emails, when you call them you wait for 5 - 10 minutes for someone to pick up and if your lucky enough to have someone answer odds are you'll get useless help. Here is an example

Last month they deducted 785.00 more out of my account than what they should of. I immediately contacted them and they said they will refund. so the next week i phone after not receiving any refund to which i am told they dont have my banking details i need to email it to them(How can they not have my banking details when they debit out of my account?) another 2 weeks go by and still no payment so i phone and wait the grueling time again and when they finally picked up they simply informed me that sorry i need to speak to the person i originally spoke to and that this person will contact me. Another two weeks later and here I am still waiting for the refund. As a side note i have also noticed on my phone since i use true caller that i get 2 second calls from rain so I suspect this is just for them to be able to say they phoned and i didnt pick up to close the tickets that are raised. Save yourself the headache people. Like i said internet is pretty good but its not worth this trouble when you need support
