Mall of Tembisa horrible service

What horrible service?!! Went and got a pair of glasses. I was. Advised to get someone to get glasses or get a second pair, I opted for the first option. I was told I would top up by 500, to my surprise I was the told about 4200 When I declined that offer to then take the second pair. Still that was declined. I am 'never coming back there again. Torga optical in Mall of Tembisa!!
