POOR SERVICE

I ordered a kids GPS watch online with Groupon in January . I sent off all supporting documentation ie proof of payment until now I have not received the GPS. After contacting the call center on numerous occasions I was told a few excuses by different call centre agents. I was told there was no stock, I was told the proof of payment was not recieved, I was told the banking details on the deposit slip was not clear. After attempting to provide all of the required details I still did not have the GPS. On the last call I was told that i would receive a refund for the money paid instead I requested for them to send the GPS to me due to me checking online and they had stock . I was notified that there was no stock available and that the price had changed since my last attempt to purchase the item. I was notified the only option was to receive a refund. From the last call i received I have not had any agent call my to confirm my banking details to arrange for a refund.
