All done within 15 minutes
I just wanted to let you know what a pleasure it has been dealing with your company. I knew the product I wanted, placed the order late on a Sunday night, and received confirmation of the order on Monday morning, confirming delivery date of Tuesday. At 8.25am on Tuesday morning I received a phone call advising delivery of machine between 10am and 12 Noon. At 10.10am truck arrivd, with two young men who quietly and very eficently, delivered and installed my new washing machine. They took the time and trouble to explain about what to do if I had any problems, refused our offer of a cold or hot drink, took out our old machine and left as quickly and as efficiently as they arrived, all done within 15 minutes. What a pleasure it has been dealing with your company. I hope the machine is as good to us as your company has been. Thank you so much. Lesley, Caboolture, QLD
Thanks for the great customer service
My mum's new Microwave Oven was delivered on time this morning. She was not only thrilled with the ease of the purchase transaction, but also with promptness, with the attention of Nathan who delivered it, took away her old oven and installed the new one. Thanks for the great customer service!
I will certainly buy from Appliances Online again.
