TERRIBLE INTERNET SERVICE PROVIDER

I have been with Rain since 2020 and from 2021, I have had 3x 5G routers under my account. I Barely had any issues, if there were they were quickly sorted out. Between July and August 2023, I canceled the 2 as I didn't need them anymore and I am left with 1 router. I joined the my rainone package and took 2 sim cards that Rain offered. I then ported my main number to Rain, I didn't have an additional slot for the sim. Now, I read reviews on social media where users claim that Rain is deliberately slowing down their speeds and I am honestly starting to belive that because since canceling to the routers I have had endless issues with my internet. As I type this, I am using a different network, where I had to incur additional costs because my rain internet has been so slow, I cannot even read my mails. My main sim that I ported to Rain is also useless as I cannot make or receive calls. For almost 2 weeks my rain network has been down. I call in, but consutants promise to call back, but never do. I request call backs, but no calls received. I have at least 10 reference numbers for call backs. Rain is greatly inconveniencing me while I do not miss even a single payment. I am really considering cancelling my account with them. It is disgusting that most of your customers feel the same way. A cherry in top, is Rain consultants who do not speak English or any other South African language which makes it difficult to sort out your issues.
