Please stop making calls from this number that you then hang up as I answer - several of these in the last few months.
As it shows up on google search as a 'definitely linked to an IRS scam' suggest you change the phone number anyway.
It's really poor customer service to make your outgoing sales calls look like a scam, trying to 'up sell' and then asking for security details - this on the one time out of 5 that your people actually spoke instead of hanging up when I answered.
I phoned your main line to ask if these were genuine calls, and why do you hang up - 'oh, because you are ringing so many people at one that someone else answers first so we drop your call' was the general gist of the answer.
If those of us on prepay wanted a contract, we'd arrange one.
The information you have 'on file' is wrong - of course I've got unlimited texts on my $19 prepay plan, please don't tell me that I don't.
I am also pissed off, I too googled the 09 9771141 and it came up as a scam... quit fn ringing me... I AM A SHIFT WORKER, and then hang up on me after you have woken me, are you fn kidding me!!! I have NOW blocked the *fn number, I am on a prepay plan and do not need a flippin upsell wake up call. Awesome way to make me wanna change companies... what a FN joke
