This is the second time I have used QMF. My first experience was not good however I thought I would give them another opportunity to prove me wrong. QMF are impossible to contact having spent literally hours ringing the customer service support line time after time until someone answered. I found some of the support staff I spoke with to be unhelpful and vague which resulted in confusion and significant delays to my order. That said others were very helpful in sorting out their colleagues incompetence, resolving the issues caused. After the confusion that was caused I was over charged and have only just been refunded. As a result of my experience I will never use QMF again and would not recommend them to anyone.
