I had loads of problems with M&P
When I first started biking I ordered my lock, gloves, boots etc from their site.
After about a week nothing turned up so I phoned them and cancelled the entire order.
Then about 2 weeks later the day before I was due to go on holiday they debited the money for the items out of my account. I phoned them and they said the goods had come to their warehouse and were now on the way to me. I went Mental. Apparently they had no record of me ever cancelling my order.
I was left with no money for my trip and had to borrow from friends and family. They refused to accept responcibility even though I had the name of the person I spoke to cancel the order.
Then about a month later they again debited money from my account. i phoned them and i got the same again. Apparently the items had come into their warehouse and were now on their way to me.
IMO they are useless and i will never deal with them again. They dont seem to take no for an answer if you cancel an order.
My understanding is that the phone based mail-order and the website are completely seperate and most of the screw-ups I have heard have been either from the website or in communication between the 2. Eg you ordered using the web but tried cancelling on the phone.
I have used their phone based mail order a few times and have had zero problems, never used their web site though as I have heard a few horror stories.
