Harassing phone calls

<p>I got a cold call in nov 2015 selling "green" cleaning products. I was keen having just bought a guest house. The price for 1 liter was discussed and how it would be delivered and I wouldn't have to pay until next year. It arrived - 25l ! My staff didn't like it so fine i tried it. Then the phone calls start about the rest of my order. I ordered NOTHING! I tested a new products, bought more than I had verbally agreed to and that is all. The phone calls are agressive and I have put the phone down twice now. Do not take any calls from viatek - they are con artists!</p>
