Firstly Rob has been very helpful, however we ordered 2 x speakers and an amp for a graduation present for my son, and for his graduation party this Saturday. The set arrived and after setting it up according to the instructions the amp after a short while caught fire. My son explained how he set it up to Rob, Rob agreed it was appropriate and a new amp was ordered. On receipt my husband helped set the system up (my husband used to set up amps and speakers for a living) the same thing happened, the amp actually caught light again after working fine for a minute or so. My sons party is this Saturday, we now have no system to celebrate his degree success and we would not like a replacement we just now want a refund which legally we are entitled to. The system is unsafe and we do not want it. You are charging us £20 for collection. PLEASE can we get this resolved so I can buy my son a replacement system for his party tomorrow! Thank you
