Not happy at all

Good day not impressed with siko concrete pumps and water drilling, i have requested their service to drill water/ borehole for me a depth of 197 meter was drilled with a cost of more than 98000, with no pump installed on the hole, i am not sure to say something fishy with the workers or is the service they always provide for their customers, i have been contacting them almost every day for my invoice, since november 2023, but keep on taking me up and down and send me a quetation instead of a valid invoice, one of their employees keep asking me how do i want them to write it for me, they want me to guide them always hence i am saying there is something doggy with the employees, poor service and still feel i have been ****** of my money... Now i jst have a open whole in my yard that have conted me a fortune,
