Pathetic service

Yesterday I tried to purchase online with my Woolies voucher. Something went wrong, so I tried again, just to see that I suddenly have no more funds available on my voucher even though I did not purchase anything yet. I phoned the number provided and I was transferred no less than 8 times from 1 person to another, I even was put through to Absa's ***** department. Eventually a lady said I must go into the store and complain there, only they will be able to help me. The afternoon I phoned customer services and the lady informed me that they froze my voucher and it will only be working again in 7 days. That is unacceptable. I would like to purchase a number of items on sale and in 7 days all items won't be there anymore, I already lost 3 products due to this. What is going on Woolworths? Are all your employees ***********? Surely you cannot appoint people who do not even know how to transfer a person to the correct department??? I am absolutely appalled by the lack, or rather the pathetic service I received.
