Rain the worst ISP ever .

If i could give it a 0 i would. Rain is the worst there is out there. On Wednesday last week i called rain and advised them that their 5G router wanst working. They said a ticket will be open and will escalate. No one has contacted me about the issue since then. I work from home and it has been horror dealing with their so called 5G that is honestly the worst in my area. To actually try and get a quick solution since i need to get some work done. I order a 4G sim card and it was delivered through MR D. I went online to RICA the SIM. Used my account since im already a customer with them. On the update it mentioned the process will be done after an hour. I checked after 5 hours it was still the same. I then called them again and they told me since i used my initial account The passport i had used had expired and the one i had presented now is new and needed to updated in the system. Fine i sent all the requiremnts via email and i was advised it has been escalated i should wait mx 24 hrs. I did . Friday i tried calling and the agent had no idea what i was talking about she said i should restart the rica process. but they when i attempted that ofcourse it didnt allow me because the sim has already been paid for 499 AND alreday in process for RICA. Called again and the next agent also had no idea. I have been sending emails and DM's on FB but nothing is being done at all. Its going round in circles and no one is willing to help. I feel ****med by RAIN and they are so quick to take your money. This is affecting my work ., my day , my mental state. I am currently using my mobile sim card on a ****le to do all this . I am even missing calls because the only sim i have im using for work. THE WORST ISP EVER.
