I get my eye tests done at SpecSavers and pay for the eye test. I then order contact lenses on-line at Tesco's as it it significantly cheaper and just because I got my eye-test done at SpecSavers, doesn't mean I have to buy my lenses from them. Tesco's have to call SpecSavers to confirm my prescription (legal requirement).
This has worked fine for years, but this year Tesco's have twice had to cancel my order as SpecSavers have told them (a) my prescription is different to the prescription I've ordered (it wasn't); (b) I'm on a trial for lenses and don't have a valid prescription!
I want to ring SpecSavers and threaten them with something legal as I'm so p**d off with what they've done. Are there any legal rights that they're in breach of that I can quote at them?
