Law / Non-EU country citizen on tourist visa - could anyone help me with Karta Pobytu? [63]

Hi, I'm having a huge problem with this dreaded Karta Pobytu.
I'm a citizen of Non-EU country and I came to Poland with the 90-days tourist visa-free traffic.I am now doing a Staz course at university here in Warsaw, so I applied for the Karta Pobytu lasting 1 year. This whole situation of applying to get the permission began on the 17th of August...Yes... It's been agonizing ever since...

I presented all the documents day wanted from me:
letter from my university confirming that I am a student there who pays regularly,
all the electricity, gas, water bills + Umowa najmu + Zameldowanie
Health insurance, photographs, application form of course...

and the problem lies here:
The financial proof...

In their information book, and also on many webpages, it says that you need to prove having 477zl per month for living as well as money to return to your country, rent fee and the tuition fee.

In my case, the calculation would be 477zl(living costs) + 400zl(tuition fee at uni) + 900zl (flat,bills) + 1300zl (flight cost back home) = 3077zl / month

So I presented them few times with the bank statements dating from July to November. I regularly receive money from my parents, monthly 3700-4000zl.

I made a PKO bank account in late July(28th) and saved in 3700zl, which was the money for August. I didn't receive any money during August because I simply got it during late July. So there is no record of me saving in money during August. Then I saved in 3300zl on the 3rd of September. October + November were fine.

When I got the result by the post a week ago, the decision was negative!! They were saying that I wasn't proving WELL enough that I am having income on regular base....

I asked many officers as well as the lawyers about this. Some of them said that I need to have the money for the whole year at once(......) and some of them(in the visa office) said, it's absolutely sufficient to prove the income on regular bases.

I have from now 7 days to appeal... and also in 7 days, my tourist visa free will be expired...I explained this to the lawyers at al.3 Maja and they simply suggested to ask my parents for more money... so currently I have about 9000zl in my account.

Could anyone tell me some past experiences of getting the Karta pobytu and some advices?

Thank you so much for reading this long thread.... Looking forward to hearing from you!!
