Poor service, no communications from RAIN!

For three month, I've been requesting for RAIN to cancel the sim card, since I do not require their service anymore, the connection is extremely bad. I email them, they refer me to SUPPORT on their website, the SUPPORT portal does not work, it doesn't allow you to submit the request. I called ***, the voice message tells states that due to Covid-19 they are unable to attend to calls or emails, again I’ve been referred to the website. What is going on? I have asked for the termination of this sim card/contract yet you keep sending me emails that I owe you. If you can send an email that I owe, the least you could do is respond to your emails too. I wish someone had told me that Rain is a ****, I would not have activated the sim card. I hope someone gets back to me asap.
