6% is a simple collection rate for small-scale VAT taxpayers. The value-added tax of small-scale taxpayers is only 4% and 6%. The tax rate of small enterprises belonging to commercial enterprises is 4%, and the tax rate of non-commercial enterprises is 6%. You are a clothing company, not an enterprise. It should be 6%. In addition, this tax rate can only be changed by State Taxation Administration of The People's Republic of China and the Ministry of Finance in accordance with relevant procedures, and no other organ or individual has the right to raise or lower it (this is the fixity of tax).

Therefore, your taxes are not staggered. As for your colleagues whose taxes are lower than yours, I think you should find out whether they are design companies or sales companies like you. If it is commercial, it should be 4%. If it is really the same as you (legally the same), then it may be that the tax bureau has a problem with them.

There is also what you said about the non-refundable tax. First of all, you didn't pay more, so it doesn't involve tax refund; In addition, even if someone overpays, it is not impossible to refund, but it is very troublesome. This is not because the tax on the first floor is free, but because the tax has to be paid into the state treasury, and it is really troublesome to return it. The usual practice now is that if you overpay, the tax bureau will not refund your tax, but use the overpaid part to offset the money you have to pay next time.

Attachment: the unpaid nature of tax means that the tax collector will not provide you with any services or goods when collecting taxes, and this part of the money is taken away from you free of charge by the state. We usually get the corresponding goods or services when there are funds flowing out, but who has seen the tax bureau collect your taxes and give you anything? This is a free embodiment, not a collection, and it will not be given to you regardless of right or wrong.
