Very unreliable. Don’t waste your money

I signed up for a service, router arrived quick. Service was not up for 2 months. I had to make a manual payment because their debit order system wasn’t working. My service is still not active and I have been sending emails with no reply and I’ve been calling for 2 days and I’m still not assisted. I would love to get a refund so I can use another SP but I’m assuming it’s going to be a pain.
