TOM TOM PROMISE OF PAYBACK ON A GPS PURCHASE NOT F

On the 13th July this year,2015, I purchased a TomTom Start 50 for my son at Makro in Springfield Park , Durban SA. The sales attendant assured us on purchase that if we bought this GPS ,Tom Tom was prepared to pay back R400 into our account if we supp**** the invoice online showing the invoice number. This was duly done by uploading online with a reply promising payback.Nothing happened for months with follow ups from me.On the 6th November I started following up in earnest & have been dealing with a Vicky D through the TomTom Support team since then .For 5 weeks she has been apologizing and promising a payback .On the 20th November they attached a definitely hoax PDF format \invoice"showing they had paid money into my son's account. There was no account number so again I queried into which account it had been paid.They supp**** me with some ridiculous account number which certainly wasn't a legitimate bank number in SA.They also said they had paid into my son's account but his details were never supp****! The last correspondence I had with them was to tell them they hadn't paid into any of our accounts and I was therefore still waiting (28/11) False advertising at its best!"""
