I wanted to take this opportunity to provide a counter to the many issues people seem to be having with service. I recently joined Slingshot for their $60 p/m unlimited promotion. The change over was mostly smooth with one issue that I needed to contact their service team about.
There was an error regarding setting up my 'realm' and I had to call the team twice in order to sort this out. The error appears in most modems as 'username/password error' in case anyone else is having this issue :)
At all times I was kept in the loop with what was happening with my connection. I was sent a welcome letter promptly with very helpful hints regarding account management.
I have called the service team three times so far. Each time my queries have been handled promptly and everything has been thoroughly explained to me. Wait times have been sub thirty seconds. I believe I have called twice in the evening and once in the morning.
My feeling so far has been that service is their top priority and the team have gone above and beyond for me.
I am yet to test the quality of the connection, still awaiting the SMS to my phone to confirm the realm has been added but with this level of service I doubt I will be disappointed.
My thanks to the Slingshot team, keep up the great work!
