Tenants in the Hang Lung Centre in Causeway Bay have expressed dissatisfaction with the way their landlord - Hang Lung Development - is handling a proposed reduction in their rent. Tenants said they had received a 'confusing' letter from the landlord's leasing agent with an offer of a 20 to 25 per cent rent reduction. The offer would have been good for three months, beginning February 1, a spokesman for the 100 tenants involved in the rent dispute said. Retailer Peggy Wan said tenants had only one or two days, and in some cases only a matter of hours, to consider the offer. Ms Wan said tenants had found the letters confusing and did not know how to react to the offer. Yesterday, they received letters saying the deadline for acceptance of the rent reduction had passed and the offer was now null and void. 'As the deadline for acceptance has lapsed, we have no alternative but to advise those who failed to return the acknowledgement within the specific time, the said offer is hereby withdrawn and becomes null and void,' the developer said in the letter. Ms Wan said at least 80 per cent of the tenants in the building were still discussing the terms of the offer when they received the 'null and void' letter from Hang Lung. She did not know how many tenants in the building had agreed to Hang Lung's offer.
