Shocking lack of service from Rain Internet Service Provider

I placed an order for a 5G device with Rain. After hearing about the possible dangers of 5G I decided after a few days of receiving it that I want to cancel my order and return it. The device was never activated and it was still in the box. It was delivered at the end of March and I was debited for the entire month of March and then 3 days later I was debited for April. Rain is considered an essential service during lockdown and yet to date, which is the 10th of May (level 4 lockdown) I have not received any assistance with regards to cancelling my order and getting refunded despite the numerous emails and online messages that I’ve sent. My account was debited again in May. I am unable to speak to anyone and nobody responds to their online message service or emails that are sent to their so called support centre and there’s no way to cancel the contract online as there appears to be a glitch in the system. This complete lack of service is beyond shocking!!! They are quick to take your money and deliver their device but after that they do not give a damn.
