On the 26 of October, I received an email from Reebok offering me 50 percent on the second item bought for experiencing technical issues on their website. I immediately selected two qualifying items however the discount was not app****. I contacted them and even today I do not get assistance. I've been asked to delete cookies and so forth, nothing works. Am I being ****med, Reebok?
