GAME4U MUSGRAVE - Pathetic and Unprofessional Employees

I received a Gift voucher to the value of R500 in December 2016, In 2017 i went into the store and asked them if the voucher is valid, i was told the voucher is valid for 3 years. In 2018 i went back to the store to redeem the voucher and was told that they need to consult the owner of the store, they took a picture of the voucher and gave it back to me, I asked them how do you intend to contact me if none of my contact details are on the voucher itself. The guy give me a page, the size of my thumb that he tore from a piece of paper lying on the counter and i fill it in and he then says he will contact me during the week. I kept contact him for the last three weeks and everyone at the store who answers the phone says they will contact me soon. This is very bad service considering my friends have bought on numerous occasions from this store. GAME4U MUSGRAVE - You guys are extremely cruel and unprofessional!!!!!!
