Very very very bad service and runs away with your money

I got them to come look at my fridge. They said 840 a re-gas. They put in the wrong gas and messed up a R17 000 fridge! Phoned 100 ties. Ran with the money! No apologies nothing. Burned the PC board. They knocked the velve with a tool . afterwards I find out that they google how to repair fridges! Be careful! I send messages, WhatsApp, calls. No responce! They said it will be fixed ,now the fridge goes 20+ degrees and melts everything! ********!
