21 ч 45 мин, 26 ноя 2019 г. - Message sent to Lorna, The blinds were beyond repairable so taken them off the wall completely.
Also took a look at the shower room and no blockage picture of the drain pipe.
Also notified that there is no blockage and that other tenants had just said it drains slowly. Will be in touch as soon as I have curtains/blinds.
