Just use a different ISP

I moved from one apartment complex to another and was assured (on multiple occasions) that the transition would go smoothly.

They didn't cancel my old subscription, and my new subscription was activated before it was supposed to. As a result almost 3 times my monthly instalment was taken from my account.

I called them, they acknowledged their mistake and told me a refund would be in my account within a couple of days.

A week goes by and I call to find out why I haven't received my money yet. I'm told that the person in charge of my case is in a meeting and that they'll call me back afterwards.

24 hours go by and no call. I call them again, this time I insist on holding until the person I'm supposed to speak to is available. After an hour of waiting on the call, I'm told that my refund has not even been logged yet.

That money is very important to me and I've explained to them that I need it back ASAP. Instead my refund was processed a week late and the actual refund will likely take place by the time my next salary has come around.

Thanks, Supersonic.
