No guard for consumer.

On 15 March 2018 I bought a Body glove tempered glass screen guard from Vodacom shop Eastgate. That same evening it came loose. It did not stick to the cell phone screen. The next day 16 March I exchanged it for another at the same shop. This one lasted until 6 April 2018 and I noticed spots on the glass that could not be removed. I discovered that the screenguard was loose. I tried to Return it on 8 April 2018. (3 weeks later.) I was even prepard to pay in extra for another product.Management of the Vodacom shop refused because they and their system did not allow a second exchange. The consumer protection act allows for exchanges up to 6 month's later. Now I have a useless screenguard. No thanks to Voda shop Eastgate.
