Poor communication and careless customer billing

I had bloods done in Aug 2014. I was not aware that the medical aid Keyhealth, did not settle the account. The first time I heard was when they had handed my acc over to the collection company. Is it too much to ask if this company could just inform the client prior to handing over. A simple phone call or text does not cost much. Today I had to settle almost double the amount. This is very unfair and proves that this company does not care at all about customer service. Careless, cold attitude. If I ever have to do bloods again, I wish to be referred to another lab. Never this one!!!!
