Terrible Service in the Accounts department

We purchased a 100gig DSL bundle on the 15th January 2016 via online payment.<br> We set it up and everything was working fine then a few days later it was disconnected.<br> We contact [URL Removed] on their Facebook page and they say the payment never came through, but they never think to warn us or inform us. They just disconnect.<br> We pay the money via EFT and I send proof of payment through to [Email Removed] for confirmation and they activate the internet again.<br> On the 15th February 2016, they disconnect the line yet again, without any warning whatsoever, and no communication!<br> No invoice, no email, no phone call, nothing! Terrible, terrible service!<br> I demand a refund as we only used the internet for 15 days!
