I bought a pair of boots for £1.99 on 13th April and they have not turned up yet. i left a message for seller earlier in the week which she ignored, I then sent a stroppier one yesterday. She says they were posted on 15th and everyone else she posted to has received theirs. She also said she had proof of posting. I know it is only a small amount but what should I do now, this is the first time this has happened to me.
