Rain 5G "Highspeeds" at 45kb/s - No support from support

My internet connection -5G- has been ridiculously slow(56kb/s) for the past 4 weeks and I've emailed 3 support tickets, had 4 support chats and attempted to dial in more than 5 times now.

This is not okay since I tend to work from home and been forced to come into the office for the past 4 weeks. I ordered the 5G service because I connect to servers over the supposed high speed network, but have not been able to do so, but they can quickly and efficiently debit my account for their money. I have two other products with them and consider myself to be supportive customer, I even commented great things about them on social media, but I've now been forced to come to this platform and lodge a complaint. This is blatant disrespect for one of the first customers on 4G and then again one of the first customers on 5G
