Absolutely pathetic service!

Absolutely useless ISP. My connection has been down for the entire day (2nd time in the space of 6 days) and has been very intermittent. I've had to spend more on mobile data this week alone than I get debited for each month. When trying to get through to customer support they ignore your requests and try to shift the blame. Absolutely pathetic service all round. I will be cancelling my debit order and moving to a new ISP if this is not resolved timeously.
