25% sitewide sale technical error uncorrected!

Used the online promo for 25% sitewide. Money deducted, screen confirmed successfully transacted. No confirmation email received. The next day; get a mail saying that although my money was deducted, the order wasn't attached due to a "technical failure on their side". It took 3 weeks to get an e-voucher to redo it. I redid it with spare money in my savings while waiting 14 days for a refund on the first transaction. Guess what, the same thing again. Only this time I didn't have spare cash and had to wait till month end (the last day for that e-voucher). Did the transaction last night after money cleared. GUESS WHAT - SAME THING and this time I am told the voucher expired its no longer valid.

THIS mistake was (and their words) a "technical error on their side". I am being run around in circles and still no purchase!

This is appalling and I am livid at how this is handled, no one gives me a number to call although I've asked a gazillion times.

Not acceptable customer service at all - I now want to speak to a human, in upper management as this is not being resolved the current level of customer service.
