Rain what a bad service

A week ago today, we bought a Woman's health magazine as they advertised the rain network with a week free Unlimited, we wanted to see how it works before buying, at home we went on the website to activate the sim, they tell us to choose our package and so forth, we had to also give our banking details, woops there goes the money off, no sim activation, and we get an invoice for the 1st of august for R479, not taking into consideration it is not even a month and the sim is supposed to be a week free, also my pay is only in the middle of the month. I have in vain tried to contact the support no avail, multiple messages left and many excuses on Facebook, their call centre is not available due to COVID, seriously is this how you want to grow your business in South Africa, my family and I would love to be clients but no one can give us answers. They allows you to leave one ticket at a time and not even resolving it, WHAT TO DO
