Ldr refund and selling wrong engine

Bought engine for 55k. Cdc. They send cff. Then almost send cjc again. I canceled the order cause they don't have th engine they invoiced me for Keep on trying to sell me a wrong engine. Returned wrong engine. No they play around to refund my money. They don't answer the phone unless you phone from difrent number. Very bad service. This is going on for 3 weeks now. No result just lies if you get hold of them.
