This company would allow their customers to suffer serious bodily harm and even die before offering alternative accommodation. I am staying in a holiday lodge and have 28 days booked. Property is pleasant enough and adequate for our needs but after a 5 day stay the CO2 alarm (as stated in the property details) started to go off continuously at 8.30am in the morning. I contacted Sykes at 9.30 who suggested the battery needed replacing. There were no spare batteries on the premises so they arranged for a maintenance person to come and replace the battery. We went out for the day but received phone calls to tell us the alarm battery had been replaced. When we returned we could hear the alarm from outside as we parked our car. The battery had been replaced and I was assured the alarm was working correctly so this indicated a real CO2 emission problem. I phoned Sykes again. They suggested the maintenance person hadn't correctly tested the battery and it was just resetting. I had a shower which meant the gas boiler was working and the alarm went off again. I phoned Sykes and told them the property was not safe. They told me they couldn't authorize alternative accommodation until they received permission from the owner who they were having difficulty contacting. They promised to phone me back as soon as they had managed to contact the owner. The phone calls went on throughout the afternoon until I was promised at 7pm that a manager would phone me back and make 'an immediate decision'. It is now 8.15pm. I have had no call back from Sykes and every hotel in the area is fully booked. We will be sleeping in our car rather than risk death in the holiday home we have paid £3,200+ for a 28 day duration. I am disgusted that Sykes have so little care for customers that they have no emergency process in place. I will certainly never use this disgusting company again.
