Such cooperative people it's a very pleasant change
Hi, I would like to compliment the manner and quality in the way I was
treated with your company from my one and only call. I needed a frig
in and I had a particular size space and I needed it the next day. I
called and I was put through to Colin. I explained my situation to him
and that was the end of it. He just kept at it until he found what I
wanted and what would fit into the space available. I was unsure and
he reassured me that he would send one the next day. He even said
don't pay if it doesnt fit send it back. At around 7.30am the next day
i got a call advising me that the frig would be arriving between 8 and
10am. Sure enough at that time the guys turned up measured the space
then brought in the frig. Perfect fit. Thanks. It is very rare today
to be treated by such cooperative people it's a very pleasant change.
Thanks again Frank Frank, Bellevue Hill, NSW

Very helpful and friendly
The Bosch Front loader has arrived and been installed, a little over 24
hours from ordering. The phone calls to advise when delivery would be,
were well received and the actual delivery personnel were so very
helpful and friendly. You have my complete confidence and trust if and
when I need other appliances. Meryl, Annerley, QLD
