Ok so I have some customers from SouthEast Asia, not going to name the country but you can guess which one. Quick clue the country has 1.7 billion people and a little over 300,000 toilets. lol Anyways I ran a 10 inch drainage ditch for them put some soil over it and seeded it. They wanted more soil so I added 4 yards of soil and reseeded it. A week later, in September, it rained and washed out about 1 to 1.5 yards of soil. I added more soil. Then at the end of the month I billed them for the job. I discounted the price to 65 a yard for installing the soil which I paid 30 a yard for. I received payment minus the soil job saying they wanted to revisit it. Every bill since then has been the same way. So today I told her I can't continue service until paid. Shes still trying to talk me down. I won't budge. Any ideas or advice.
