Struggle to get refund e gift voucher

On 11 July My husband bought a sterling silver ring from bash online. An hour after purchasing item he was notified that it was cancelled due to no stock. Bash informed him via email that they are processing an e gift voucher. Up untill today he has not received anything! We went to sterns as well as american swiss to to enquire regarding the gift voucher. In store Bash was phoned 4 times and we were informed each time we should wait 5minutes to receive the e gift voucher via sms on his phone. Nothing! We waited over 2hours in store as he wanted to use it to purchase a watch for me for my birthday. However still no refund voucher. We are truly disgusted and dissappointed in the level of service we received from Bash. So pls people do kot buy from Bash rather buy your items directly in store!
