Rain sucks!

This is the second time I am complaining about Rain on HelloPeter. My father purchased a sim card from Rain in April and until now he still can't activate it. He is 60+, he lives in BFN, I live in CPT, I asked him to download AnyDesk so that I could assist him... he battled with that too. So as you can see, he is not tech savvy! And I have been begging Rain on social media to CALL him and go through it with him over the phone. Nobody has done that YET he has been billed every month since APRIL! Is that fair? Absolutely not! This is frustrating and we are not getting the help we need. Please.
