Unsettled debts

Q: A brother uses his cellphone as a modem. Unfortunately he contracted a virus. The effect of this was that as soon as he put on his phone the counter was just running. The result was that his account which normally comes to about R250.00 came to R5500.00. After investigating it was found that this was caused by the virus.

The service provider says that it is not their problem and they want the account to be settled. Will it be permissible for the brother to pay this account using interest money?

Q: A few years back, I owed money to a company. A family member who was owing me money undertook to pay it on my behalf in lieu of what he owed me. I have recently found out that this money was never paid by him. On contacting the business, they told me that it has been bought over by another company, but the person I spoke to was unsure whether the company had taken over the debtor’s book of the company and was of the opinion that they had only bought out the stock holding. I have sent them numerous e-mails trying to establish if this was the case, and if so, requested that they provide me with the details of the previous owners so that I may repay this amount. To date, I have had no correspondence from them and find myself in a predicament of not knowing where I stand. What should I do in this situation?

Q: I have a question regarding debt. In the UK universities are now charging £9000 per year or so to cover the costs. If i take a student loan which is wiped off after 30 years, what would happen if i die and havent paid it all back? Also i want to ask the same question regarding a house mortgage?
