I posted this on the maxi cosi facebook page and basically got a response to say there's nothing they can do to explain the marks or will they refund me or replace my seats!!
I really didn't want to have to do this but you have Left me no choice! At the beginning of October I emailed you about the 2 x pearl seats my daughter uses and has used for 2 years. She always moans her back hurts in it and just shrugged it off that she didn't like being in the car. She always had this 'mystery bruise' on her lower back as well that I put down to being a toddler. Anyway I finally put two and two together and worked out it was the back of your seat causing her pain/discomfort and worst of all marking her poor back. You kindly collected both seats for inspection, upon my several requests for a loan seat you told me I was on a waiting list. I have a newborn and a toddler and do not live within walking distance of nursery and you decided to leave me 4 WEEKS AND 2 DAYS without a car seat before you finally emailed me a report which basically said there was nothing wrong with my seats and it was my positioning of my daughter in the seat causing this issue. I then sent you a reply on Tuesday afternoon to say how unhappy and disgusted I was with your service and that I in no way feel happy or safe to put ANY CHILD in a pearl again. I requested a refund for my seats and bases. You didn't even have the oyrdacitie to reply to my email but instead I randomly just received back both my seats today with a repair form stating 'returned as requested' I AM ABSOLUTELY DISGUSTED AND VERY SHOCKED with your customer service. I always thought of your company as a big repeatable company but am quite frankly so disappointed with how you have treated me. You say you take safety very seriously which is why it apparently took 4 weeks to inspect my seats but I find that very hard to believe. I have a few screen shots from people that have had the same problems so it is obviously a disgusting and shameful design fault that you are clearly taking no responsibility for.
I heard nothing so a week later I posted this:
Maxi cosi it's been nearly a week since you sent me my seats back although I requested you not to and have a refund instead you acted differently and just sent them back without responding to me, against what the consumer wished for. I'm still awaiting a reply!!
So they finally replied to basically say there's nothing they can do as they found no fault...so I am left with 2 car seats that my daughter refuses to sit in!! So disappointing from what I thought was a big reliable company!!
