Stephen's Lawn Enforcement

I accidentally paid an invoice twice for $I alerted the company right away when I noticed the error and sent them screen shots of the cashed checks I sent themI had to contact them many times asking for a refund of my double payment before they finally responded and said they would send my refund and asked for my address where they could send my refundI sent them my address immediately that same dayThat was over a month ago nowI have followed up numerous times since then asking for my refund back and they are now ignoring me completely and refuse to refund my money to me or answer my correspondence
