Hi everyone can somebody help me?I'm on income support with a top up for sickness.I have a medical condition which means i can't work.But i'm not ill enuff to get dba.The thing is I have two credit cards and a catalogue.The first c.card i transfered balances over last november.one i have paid fot the other balance is wiv capital 1 of 580quid.then silly me got this new card a gold one off llyods tsb wiv 1500 on it and spent on it.next month the 0% deal is over and i owe them 2,300 something.then i went and spent on my old card and now thats back upto 380quid.i pay 100 quid on the highest one each month and what i can on the other and i haven't used both of them in the last month.my catalogue is about 800quid i owe,i pay 80 quid on that a month.i'm a single mum and manage to do ebay to get what i need and started to put away for xmas wiv the money i make on that each month.but i'm really starting to panic now as this credit card is gonna shoot up!i have tried to apply in the last 3weeks for a 0% deal to transfer the cash over but been refused.i always pay more on my cards then the mim payments.i don't want to appy for to many cards in a short period as Martin says it affects ur score.i have never missed a payment,but i took a look at my report last month and it did have when i never paid my phone bill for a few weeks.i would love to apply for a loan but cos i don't work i can't get one.which credit cards would i be able to get to transfer over too?i need a card that will accept that i'm not working but not having any luck.one that i won't spend on just to pay the balance off i would do.i'm sick to death of being in debt and really want to be better off for me and my boys.as you can tell i have never been to good with money but since doing ebay it has changed my mind about things .what i haven't got i can't have so my new moto is "to only spend what is in my purse not what is on the plastic".please someone help me i really need to know were i can apply for a new card that accepts unemployed people who are sick but not on incap benefits.thanks lorraine
