TomTom Money Back. Still waiting for Feedback

I purchased the promo at due south where I qualified for R500 cash back<br> <br> I uploaded my invoice along with answering all the questions on the 29 June 2015. I immediately received an email stating that my money back request will confirmed within 7 working days<br> <br> To date I have not received any feedback.<br> <br> I tried call your support line and waited almost 30 mins and eventually hung up<br> <br> Can I please get some feedback into this matter?<br> <br> This is really disappointing coming from a brand as big as TomTom
