Hi thanks for your question. My name is***** can assist with this.
If you agreed that the knocking noise etc., would be put right, but it was not, then they have not fulfilled their part of the agreement to get it put right.
Yes, and if they don't agree to put it right (if you want them to), then the usual rule is that you can go get it repaired yourself (i.e. to put into effect what you agreed - no more than that!) then charge them for that cost.
Is there anything else you would like me to answer about this for you please?
Please remember to rate the answer for me before exiting the chat. Thank you!
