Very disappointed

Very disappointed with the GloBrush Pro - 3 In 1 Thermal Brush I ordered from them. First of all it took 2 months for my item to arrive. I was promised a R500 voucher for the delay (that I still have not received) - Not that I will use it in any case. They promise the moon and stars, but when the product does not do what was promised, you are stuck with a product you can't use. They do not refund opened parcels - Explain to me how I should know a product is not working as it should if I don't open it? Getting feedback is a nightmare too. Very sad that I spent my hard earned money on this.
