EDGARS HAS TERRIBLE CUSTOMER SERVICE

On the 25th of Oct I physically went to Edgars Maponya Mall to go look for the hauwei p8 lite cellphone. I was told the store has it in white and i am looking for it in gold. Norman (the guy that works there) told me that on monday (26 Oct) they recieving new stock so probably they will have the phone in gold. I have been calling the stores and no one helps me. If its not the lines being busy, I am put on hold for more than 10minutes. The head office number ***) that i called on Saturday suddenly doesnt work anymore wherelse it was working just fine on saturday. i cant keep calling all the stores in johannesburg, its time and money consuming. I tried the *** number and its a dead line, it goes mute after making the second option. WHAT DOES A PERSON HAVE TO DO IN ORDER TO GET HELPED????
