Pathetic customer care

I transfered money into wrong cellphone number on the 25th ,sadly phone number seems not working it's always unavailable. I went to capitec they were offline called customer care number the pathetic advise was I have to get a lawyer to get the R2000 back. How much will I pay for a lawyer? On this covid19 situation honestly this is frustrating. I am not committing ***** I want my money back that's it.
