Mellins I Style

My mom went for an appointment a month ago, it started at a bad foot with them never writing in the booking even though she made the appointment via the phone a week before. Then after the appointment which almost didn't happen, about 2hours after, they phoned to say they forgot to do another test, can she come back. Not noting that she doesn't live close by and never mind has time and can just come anytime, due to their fault. But because my mom is a sweet person she went back, spent more money on petrol and did the test they forgot. She then paid in full for her glasses (31 March 2022) and off we went. It is now almost a month and she has not heard anything from them and she doesn't even know if after all the other 'faults' that her expensive outing would have been worth it and if the glasses will even be right. This whole experience has been devastating for me to see how people get away with abusing kind people and getting away with it. I will never let my mom go to Mellins again.
