pathetic in every way

I went to the store today. This sales guy approached me and told me if I buy items to the worth of R300 I will get R100 off. The more I purchase the more I will get a discount. I proceeded to to go ahead with this deal. I found a pair of jeans for R250 and then decided to buy 2 jeans for R360 so I can a R100 off. When I was done I asked can I plz have my voucher so I can pay, Shockingly he told me for me to qualify for the discount I must now open an account, I mean now really, anyways I proceeded to go ahead and he told me it will take 2 min to open the Acc. It was gone 15 min and he was still battling to enter my details, my wife was waiting for me with our baby outside another store and this is happening. I became angry but remained cool, after he was done after taking 20 min he said I will get an SMS that I'm approved. Then again I asked him for the voucher and guest what, he said once I get the SMS after 24 hrs I will get the discount. I was so devastated and I felt totally betrayed by this ****** portraying Edgar's in this way. I immediately told him I will report this incident and went away. I purchased one jeans only in the end. I am disgusted and don't even want an acc.
