Worst service ever

The worst service ever ,they tell you they have a special and when you get to the branch it's a different story .You then agree to their available package and choose a different frame from the now agreed upon package and a day later want you to change them again😠.Then you ask about the payment option they tell you about an option they have but they don't give you the full info then that package is not available because...You complain about all these things and the likes of Maggie call you already with their minds made up to say we have failed you as a company but then so what attitude.I've appreciated Mellins services for years and if I were to rate them for prev service I would give the 30\10 that's how exceptional their service was but the service I got this year was the worst I've ever received from them .
