I am going to lose my job because of Rain Service Provider

We invested in Rain about 2 months ago on Unlimited 5G Home Basic Plan that is meant to provide 25Mbps download and upload speed. This was for a new remote position that I started on 3rd October. This is a job that is meant to provide for my family and pull us out of dire financial circumstances post Covid-19. The internet speed and connection has been nothing but horrible with download speeds of almost 0.9Kbps during peak hours when I need a strong connection. I may now lose this job because of the consistently bad internet connections. I logged more than 1 ticket, they since promised that the Advanced Network Department will come out and investigate the network tower nearest to our location, I've made repeated calls and follow ups, nothing has changed. I cannot believe I am about to lose a very good job over Rain's poor internet connectivity ( as if jobs are easy to find). I am so let down by this service provider. Tickets logged with support that we are yet to get feedback on regarding this matter are: *** and ***.
