Currys

My wife recently bought a dishwasher from Currys she was charged for delivery and installation and was not told about the fact that currys would not connect it for any variety of reasons.When the machine was delivered the driver/fitter stated (within about 2 seconds) that it could not be fitted for health and safety reasons.
I called a plumber in at massive expense then phoned Currys to complain that my wife had not been warned about any possible difficulty with fitting the dishwasher and regarding a refund of the fitting fee.
Customer services immediatly adopted a defensive posture but did say that "mmmm maybe the store could have explained this better".During this conversation the customer advisor stated "Well you dont expect us to pay your plumbers bill do you?".
I phoned the store and the following day i was informed that if i bought a waste and water pipe the they would fit it (I thought that was odd because surely me buying a couple of pipes which i would not have a clue about would be a health and safty issue in itself).I declined this offer because i know as much about plumbing pipes as currys seem to know about customer care.
I was advised by currys that my wife should take her receipt to currys to get the £14.00 refund.
She tried this today (A saturday) and was told that she had to come back during the week to carry out a refund,My wife explained that she could not attend currys during the week because of other commitments and thats why she had come to the store on Saturday.The member of staff then questioned my wife about her work hours explaining that the store was open till 8pm so she should be able to get there!!.
I phoned currys customer care who stated that the "system must have been down at the time",I explained to her that my wife was not told that and that she was told quite clearly that this kind of refund had to be done during the week.I explained to the customer care rep that i felt that we were being picked on because we had complained about this service or lack of it but was told that this was not the case.
£14.00 is not an earth shattering amount and i dont care so much about it.I am however concerned that currys do not think we have a valid point or do not seem to care that much.Perhaps if they stopped for a moment and considered what the word "care" actually means and they would cease to exist as a company without "customers".
