Skodi Jabulani Store manager- terrible customer service

I bought an iron(Defy) on ********** 8 from Jabulani mall. This morning I go back to the store as the iron has stopped working, I get to customer service and the sales lady tells me that I can not be helped as i have misplaced my slip, having the transaction on my cellphone (confirmation of purchase) and date/time of purchase wasn't good enough for them to check their in store records. The lady at customer service the refereed me to the store manager (Skodi) who also had no interest to help me, told me that I have to go draw a statement from my bank where the transaction is showing. The store manager further explained to me that the merchant slips are already at the bank for that day and the till slips already at head office.

So since I don't have the slip and Game Jabulani is not willing to help, who am I as a customer who spend R444.00 on an iron hardly 2months it is not working. I must say this is bad customer service from Game Jabulani, other branches and different stores go an extra mile to assist a customer. I need from someone from head office to intervene and offer training to the store manager which will then decent to the rest of Jabulani branch.
