Whilst MM say to allow 7 days between you sending your item and them receiving it they actually mean 7 working days. Also, they don’t necessarily count the day you post it as one of the 7 days. In non of their comms do they say “7 working days”. Also worth noting that Royal Mail seem to introduce a lengthy delay between marking your device as delivered and it actually reaching the MM warehouse, something you have no control of but MM seem to make your responsibility in terms of delivery time.
I chose to use MM this year, instead of eBay, for ease and less stress but, for me personally, it has been quite stressful. IPhone posted 9 days ago, marked as delivered 4 days ago but still not scanned or processed at MM warehouse which is when they deem it as received.
