Bad customer service

Ordered linen online on the 28th, taking advantage of their 20% off, and also used a voucher I had won in their Play and Win competition. I received an email on the 3rd, alleging that my delivery had failed for some reason. Upon enquiry, I was informed that my goods were not delivered as they couldn't get hold of me (my phone was on the whole day) and that there was no-one at my house or that the driver couldn't find my address even though I have had numerous deliveries from Woolworths with no hassles(I was at home the entire day recovering from the week's travel). Now I am told to re-order the goods, but that the 20% off promotion is not running, with no mention of re-crediting my voucher. This is a *******, and their driver's error (I suspect he never came this side of town tom start with) is now made mine. I will not be ordering anything online again.
