BIG FAT ZERO

I signed up for a contract with Openweb at the beginning of November. The SIM took 10 days to arrive. It is meant to be a 2TB data package deal at "full speed". I can get maximum 2Mbps. Today, 2 weeks after I received the SIM, I get a message saying that I am out of bundle. That is not possible given that I only get 2Mbps connection speed. And then of course, there is no service when I try to contact them on their Whatsapp support line. Zero response.
