Shocking service

Pathetic service. I ordered some capsules online and then lost wi-fi signal, so the order timed out. I had used a Discovery voucher to pay for the order. Do you think I can get refunded? Phone calls, emails all come to nought. I have been told a few times now that " this has been escalated" which is corporate speak meaning "rest assured, we are going to continue to fob you off".... and we will certainly not be helping you. I suppose if they ignore enough customers when this happens, they can increase their profits, as they don't dispatch the order, but keep the payment. A very ***** practice, at best...
