Worst customer services

Honestly the worst customer service experience - in store and online. Desperately trying to return a faulty fan, Clicks will only refund to the credit card used to purchase. I don't have the credit card anymore (changed banks) and so the alternative is a voucher. The voucher option is no good, as there are no alternative options to replace the faulty fan. Here i am, still with a faulty fan, no refund given and one very frustrated customer. It took well over my lunch hour trying to get someone to assist. Instead, I was given the customer care number to phone (using my own airtime) ... a waste of time and money.
