If talking directly with the neighbours does not lead to any improvement in the situation, you should ask the landlord or landlady in writing to deal with the disturbance within a reasonable period of time. At the same time, you can mention that you will cease to pay rent if no improvement occurs within the said time limit, withholding the money in a separate account. You can ask for a reduction in rent so long as the disturbance persists.
If the neighbour continues to cause the disturbance despite a written warning from the landlord or landlady, the latter can reduce the period of notice to be given to 30 days to the end of a calendar month.
