Visa problems...

I've been trying to extend my visa for the last week now. It expires in 8 days, the same day as our flight up north to Harbin. The first time I went there I was sure they'll be able to give me a tourist visa for the rest of my stay (until my flight back in the end of April), but the guy there told me that after a study visa I can only get one month tourist and then I'll have to leave the country. I was annoyed and asked if I can get a business visa - coz I "work" for my fathers company. He told me to go to booth number 12 - where their chief officer sits. So I did, and this guy tells me that I need these and these documents for that and so on. He wasn't very nice I must say. I called my dad and he asked one of the ppl he works with (which I know coz 2 years ago I worked with him too) to help me. This guy works for a company that is not located in Shanghai, and I need documents of companies from Shanghai only. So he asked a friend of his to help me. This guy is a journalist and knows another guy here that has a little trading company. Story goes on and on - in the end after a hell of a day (seriously one of my worst days I had here ever) wondering around the whole city by taxis and subway, going to the visa office twice (and it's really not close to anything- it's in the other side of town) going everywhere to get certain documents, after waiting in line for about 2 hours, in the end the chief there looks at me at tells me that this company is not good. "How do you know them?" he asks. I tell him that our company knows this one through a company in Wenzhou (where the other company is located) and that we do some business with them too. He looks at the documents and says that this company has bad reputation (I'm not sure he even knew what he meant by that) and that I can apply for the visa with this company but there's a good chance I'll get refused and asked to come for an investigation to see what relationship we have with this company. I told him that it's just a small company we work with here, and coz they said they needed one from Shanghai this is the only one we have. I added that we have big business with other companies in China- but not in this area. He scared me saying that if I get refused with this company I'll have to leave China in 10 days. Tears were threatening to burst out of my eyes, while he was asking "so... what do you decide to do?" I took my things and told him I'll find another company, and felt so lost and humiliated - running back and forth to that place with a different document every time- being told- this is not good enough!
I called my dad begging him to check if he really doesn't have contacts in Shanghai itself. He called the guy working for him in Beijing, who reminded him kindly that they do have business with a really big company in Shanghai- a company I was even in touch with 2 years ago... My dad told me that and I went home, waiting to get the new documents- this time of a reputable company...
Tomorrow I'm meeting a guy from this company, in the visa office. I hope it'll work this time... I'm exhausted from all this crap. The thing is that if I'll have to get the tourist visa for only one month I'll have to go to Hong Kong to get a new one (coz it's considered out of China) which is gonna cost me a lot of money I don't have...
I really hope that this time it'll work, and that yesterday's experience wont influence my luck in that office- coz I have to go to that chief again - maybe he wont be so nice...

cross your fingers again pleaseeeeeeeeeeeeeeeeeeeeee!!!

and i'll just put this one thing for luck
