I Don't Owe You Nothing!!!!!

I am sick and tired of lancet phoning me, harassing me, threatening me to hand me over for money I don't owe them! In 2012 my husband went to ER in olivedale hospital and had I blood test done! They quoted me, and I paid them in full cash. They gave me a receipt. Two months later I received a call telling me I owe them money, I asked them for what as I paid them in full. They asked me to sent them the receipt via email and I did. They never responded to that and to this day they are threatening to hand me over. 2 months ago my husband had some blood work done again and we being stupid went to lancet again witch I regret very much! They quoted us we paid it before blood test was done, nowhere was it stated that it's was estimated and nobody informs you! Now today I was told I owe them R1500 on top of the R3600 I was quoted. I have paid what was quoted to me, I owe lancet nothing, and I won't pay you whatever amount you are tumbsucking, hand me over take me to court do what ever you want. I will never put my feed in side a lancet lab again! You lancet are a bunch of schemers, ********ting people. Shame on you lancet, this is really disgusting. I am taking this further!
