Maintenance is cheaper than fixing something when it breaks

So this review is not about bad service or rude people,I actually enjoy three rivers slater and their staff, my only complaint is that they do not do proper maintenance on their equipment,in petucular their treadmills or airrunners,this is specialised equipment and needs a properly trained tec to service them,but the maintenance guy at slater us not trained to fix them and they come back from maintenance worst than when they left,this is very strenious on people with back or knee problems,come on guys we pay our fees so please give us properly maintained equipment.It is way cheaper to maintain equipment than paying for repairs when the break.
