Being charged 'Processing fees' when buying on installments

Q: I am seeking guidance regarding a matter related halaal and haraam. 

I live in the United Arab Emirates, and we are not very well off, we struggle at times to buy things apart from the necessities. 

There are two fintech companies TABBY AND TAMARA. 

Tabby was shariah compliant initially when they started, splitting each bill into 4 installments and so was tamara. Tamara is still 4 installments. But tabby has now introduced installments in 6 months, 8 months and also 12 months and when they started here, there was a fatwa on their website too, they don't say that it is interest, there's an extra amount that they charge which they call processing/service fee, I want to know is that interest? I have multiple payments spilt across because I did not know it and just realised it, also because initially there were fatwa on the tabby website. For tamara, there is also a fatwa and they have mentioned names of scholars who have given fatwas 

All of the shariah resolutions are attached on their website too, so I want to know if what they calling the 'Processing fee' is not interest and allowed for me to use as it is really helpful, and if it is not, then I have multiple payments spread across both companies and I am not in a position to pay it all off as we struggle big time financially. As someone striving to act in accordance with the teachings of Islam, I want to ensure that my actions are pleasing to Allah Ta'ala. 

Issuing talaaqs from a fake Facebook account

Q: If Ahmed, with a different name, opened a Facebook account and wrote to a scholar of Islamic jurisprudence (fiqh) from this account, saying, 'I have divorced my wife with triple talaq, what should I do now? How can I take her back?' (when he hasn't actually divorced her, but is in doubt and told the situation as if it happened just to learn what to do if he were to do it), what is the meaning of the quoted text in this context?

Delivering haraam items

Q: I want to ask about earnings from food delivery services in a non Muslim country/community. Uber Eats, Door Dash are the delivery service name. 

The delivery is not containing any alcohol, etc. but sometimes some foods containing pork products. Either cooked or sometimes grocery items contain bacon, pork products, etc. Are the earnings halal or permissible by a Muslim?

Selling rizla

Q: I have noticed that my father has been selling filter/rolling paper (rizla) in bulk such as in large boxes to possible retail customers. I would just like to know whether it is permissible to sell such an item given the nature of its use?
