[sammasom]

i took out a loan with my bank for 5 thousand pounds i am disabled and i was getting the low rate of mobility middle rate care ,and severe disability allowance ,i have an ongoing illness ,my bank told me i should take out ppi protective insurance ,which i did .i had some financial problems and was having problems paying for the loan ,so i applied for the insurance but was told as i had an ongoing illness i could not get it,i would have to get another illness ,6 month later i was diagnosed with an underactive thyroid ,they told me after a lot of phone calls and complaints that they would pay me for one year ,now i am still having problems ,my husband lost his job ,although his name was not on my account ,and he has had to give up looking for work as he is now my full time carer as i have now got fibromyalgia ,and now we are both on benefits,should the bank have sold me the ppi if i could not use it i would be gratefull for any advice ,thank you sheila ,
