That is correct, on a phone call we offered to replace, but they had already proceeded with the rectification. We did not give any agreement for them to carry out the work.
Could you please advise if there is a case to answer, or should we just inform them we will not be paying the invoice
Just a quick question, for future knowledge should we ever need. With regard to the rectification. Are we liable only for the part that "failed" to be replaced as this was where our involvement ended or are we liable for the whole re-work to be carried out, namely manufacture of the whole balustrade.
