Well still not sorted. Apparently they are right and I am wrong.
Have spent the last couple of nights in tears over this - at the minute I will actually earn a couple of hundred pounds more being part time than I am just now on a full time wage. Make sense of that one?!?!?!
Fortunately my friend has come to my rescue. Her hubby is an accountant, so if I cant get all the paperwork emailed to her, she will get Jim to run the numbers for me, and then armed with his sums I can tackle South Lanarkshire council again, and this time I will not get off the phone till it is sorted!
argh - how stressful is this.
