Hired a car from SuperU Tintenaic early in June for 5days. On collection the vehicle was neither…read moreclean inside nor outside and the tyres were under inflated. After a few days my wife and I started to get sore throats and during the last couple of days we developed nasty coughs and chest pains which caused us to be fatigued so we arranged for a French friend to assist in returning the vehicle. SuperU Tintenaic stated that we had to return the vehicle fully refuelled with a receipt showing we had purchased the fuel at their store and that it should be clean inside and out! we returned the veh early as we were not well but on trying to purchase fuel at Super U Tintenaic there were 4 lengthy queues which we joined for at least 30 mins only to discover their car wash was not working; we had already cleaned the car inside at our accommodation! The check in staff who were also making up orders for delivery insisted that we take the veh to another "off-site" location to have it washed- even though it was still in the same condition as when we collected it. On returning to the check in they told us we were late and upon examining the veh they said it was not clean enough outside- even though we had just returned from the car wash they had sent us to- and we would be charged an additional 70€. At this time our French friend who is a local and wary business person interjected and told them the car was cleaner than when we collected it and their unserviceable car wash coupled with the direction to refuel at the store had caused the shambles . She also stated we were obviously sick and would not be paying any additional fees. At this time the Super U employee withdrew any threats of a penalty and signed off the transaction. Unfortunately it transpired my wife and I had suffered a mostly nasty viral infection to our sinuses, throats and chests from the hire car's air conditioning system which has incapacitated us for 2 weeks! Conclusions:- it has been intimated that there is a racket ongoing re the additional fee of €70- our French friend recognised this and "stamped" on it; does Super U condone the policy where the hired veh must be refuelled and washed on their specific site with receipts shown as proof; does Super U ensure the air conditioning systems in their hire fleet are properly treated to remove viruses and life threatening bacteria or are they more concerned with imposing €70 penalties for allegedly dusty vehicles? The nasty viral infections have laid us up for two weeks and will require further treatment at home but I warn all potential hire car customers at Super U Tintenaic to be aware of the health and financial risks which could occur- we , to a degree, we're lucky as we have a savvy and well informed local business person with us!
