Their billing department sucks!

I paid them every month on time and manually for two years. Twice had they billed me via debit order even though I had paid them already, so I reverse my debit order. They asked me why I did that, and then I said that it is because they billed me unnecessarily -- I had already paid. Well, some dipsh*t in their billing department ended up marking me as a bad payer, so I was unable to get a new iPhone through them.

Guess what? Great! I do not need this sh*tty, disorganised business to get the tech that I want. Guess what else? My entire family will be moving away from their services ENTIRELY because of their BS.
