Poor excuses from TCG

We've been using TCG for years and I've had just about enough of the constant excuses of new drivers in our area which results in them not collecting parcels as per their SLA. In less than a week I've received the same excuse 3 times, there is a new driver, "but we will send a recovery vehicle tomorrow to collect". Then tomorrow comes and goes, and still parcels are not being collected. We operate an online store and have our own SLA with clients which we can't deliver on as a result of TCG's poor and unacceptable excuses. Why not increase your business efficiency by giving drivers Garmin's or something? As a transportation company, I find it ridiculous that you are unable to locate an address, being a new driver or not - this is the worst excuse for a Courier company.
