PATHETIC SERVICE!!!

I purchased a fitbit watch from groupon on 30th December (Black Friday). I asked my husband to make a payment into thee account with an amount of +/-R249. He accidently made a payment of R669.00. Because he overpaid I then purchased a vacuum cleaner to make up the amount paid. I then called customer care and was disappointed to hear that my order will be cancelled due to the incorrect amount paid and the money will be refunded into my account. I gave him the account details that it needs to be paid into despite the disappointment of not being able to recieve my order. Their system sucks!!! Up until today, no refund. Sivuyile did not escalate the request. Last week I called, number 32 in the queue, waited half an hour just to find out from another consultant that he hasn't escalated the issue. Today I called again, 45mins on the phone, got the same response, that the reference was escalated last week, still no answer. The consultant today said she will get back to me within 24 - 48Hrs. I've lost trust in customer service call centre and the fact that they have such high call volumns could be the same reason as mine or even worst.
