It's easy to get credit these days, but remember credit is only credit until the point comes when you can't service it; it's then called debt.
In a previous life I was the Unit's Debt 'Advisor' and had numerous soldiers with financial problems in my office. It was an 'add on' to my primary function (on top of other add-ons) and it was a real pain in the ass.
In brief, I had to ascertain the full scope of the debt, write letters to each of the companys involved, giving them a letter of authority from the soldier saying that I was dealing with the debt, and ask how much was involved. I'd make them 'cash paid' soldiers (no money going to their bank) and confiscate their credit and bank cards, and their cheque books (I couldn't do this legally, but if they wanted my help, this was a pre-requisite) and I'd pay them enough money to live; cash. If they were single soldiers, that'd be about £20 a week and if they were married it would be more (depending on how many kids they had).
I'd then write cheques to each month to the companies that they owed money too and deduct that from their wages; making sure it all balanced.
This was no doubt a humiliating experience for many of them (and their wives who I used to request the prescence of), but I wasn't openly nasty or arrogant. I even had a big 'thank you' published in Soldier Magazine for helping one soldier out with his debts.
But, it was a massive drain on my time, and I hated the soldiers for making me do it. I considered them to be total 'four letter words'.
However, after I had a messy divorce (still not properly resolved after 7 years) I found myself in debt and hounded by collection agencies. I guess it's one of the reasons why I left the army, I couldn't do the job I was doing (it was money orientated) while I was in debt (not credit).
My advice to anyone whose struggling with debt is firstly, don't worry; they can't make you pregnant (unless you're female and let them), and secondly don't bury your head in the sand; there's a wealth of information on t'internet; read and learn; then act.
But don't worry, prioritise your debts. The roof over your head, utilities and taxes come first. The rest can 'swivel' on your middle finger if you can't afford it.
