Ripped off by orange!!!

I hate orange with an absolute passion!!! Had a contract with them (and EE ) & was ripped off,customer services were dreadful & didn't know what they were talking about!! Terminated contract...didn't want to have phone unlocked,so thought "orange pay as u go can't be that bad,at least I'll have more control over my credit"....WRONG!!! I had £5.67,sent 2 texts,then was told I had 41p left,& would I 'like to top-up with another £10?'...no I bloody wouldn't!!! Not only that,but when I tried to call 450 customer services,it said I didn't have enough credit...so that means more had been stolen from me,cos it costs 25p to call them!!! Angry,so v v angry!!! :((
