Lingua+Riga - rude, unprofessional attitude

I don't have any complaints regarding swedish language teacher- she was good, maybe a little bit haotic, but ok. But I was shocked about the owner/ administrator. She was always like lost in the office and did not know her job at all:

- when I had to pay all at once to receive a discount and there was no option to use my credit card, they pushed me to go out and look for an ATM. Since I really wanted to take a course- I was ik with that.
- the learning course was ok- as said- a bit haotic, but ok.

-on the finishing day- I did not receive certificate. I went 3 times and called numerous times, but the office admin was so rude to say that they not suppose to issue any certificates or that certificate is not included in the price, etc. Even got personal when I went there the 3rd tie just to receive my certificate and said that she is so sick of doing this job and I don't deserve it(?) and she does not speak latvian, just because she is not going to learn the language of the nation who owes everything to everybody(?). Besides that- she had numerous spelling errors in certificates in both languages- english and latvian. I had to come over and over for "new, updated" certificates. After that she announced that this is the last certificate she printed and she is not obligated to issue any(???) certifiates at all.
I was shocked about such office working nowadays... and no wonder you are not able to insert a comment in their home page, because now I'm sure- all should be fake...
