Give my courier money back

I honestly feel ****med by this company,I ordered a Peruvian weave,10 inch,which the person sent me pics of weaves they have,I chose this particular 10 inch one,then she sent me the bank details,to deposit for courier,which is R200, thereafter I sent proof of payment,after accepting the mandate of the weave,which was R1600,they called me and said they don't have the 10 inch in-store,they have 8 inch with more volume,it's R1900,they will send me another Mandate to accept,I said no I'm not going to do that,They must cancel,since then,they are quiet,I haven't got my hair,I paid delivery fee,and I'm sure they waiting for my pay date to debit,but anyway I don't work far from them,I'll visit them soon,****ming people with their hard earned money,mina eyami ngiyayifuna,cos kuzonyiwa
