Looking for opinions please.
A new customer called around 6 months ago to ask for help with a piece of equipment, I explained yes I can help the price for me to come out look at it is X amount, explained this is just to establish the fault and includes no remedial work and that if any parts are required or that's it's not repairable I would go away and provide a quote if they wanted one.
The initial fee is a one off fee and further works are chargeable, this is made clear on the phone and in writing via email.
I go, find the fault and its not repairable, I tell the customer this and advise that they would require a new item, they pay their call out bill, all fine so far.
I ask whether they would like a quote and they say yes, I send a quote and don't hear back, again perfectly fine.
6 months later they contact to say they have purchased replacement item themselves and want me to come back and install it within the original call out fee.
I explain that the initial fee was for the call out only and no further works were included, remind them that this was in writing via email and explained during the initial phone call.
They come back and tell me they've spoken to a few people and believe they were over charged and that they would like 65% of the call out charge back.
AIBU for not giving the requested sum of money back?
