Dear Steve,
I sincerely apologise for having a go at you yesterday on the phone regarding the 2 transformers I purchased from you last week.
After checking further the fault is clearly with the wiring in my light fittings which seems to be caused by the original transformers going bang on the same circuit which damaged both fittings.
The wiring had melted and was causing a short, which as you did say to me the safety cut outs were engaging.
The fault was clearly my end and I apologise for my conduct and language.
I was not aware that you test all transformers before despatch and it was my fault for not reading the terms and conditions which gave me all the information I needed to know.
I will recommend your company to my associates as well as display your details on our staff notice board.
A big thank you to your company for a fast, efficient service.
Mr D Brown
