Incredibly BAD Connection

Just wanted to buy something online.

So i saw i had Ucount rewards. So made a voucher to Incredible Connection to do a part payment on the item. You don't do part payments and you fail to mention this anywhere. So now i am sitting with a Incredible connection voucher that i cant use. You don't sell the product instore, only online.

So how am i supposed to get this online product in one of your stores so that i can go in and use the voucher?

I cant refund this back to my Ucount and am now sitting with a useless Incredible Connection voucher??

Your customer service put the phone down 2 times. Cape Gate and Tygervalley don't answer the phones? Your online LET US HELP says: 1. Phone the stores in another hour. 2. Phone the customer care. While i am on the line with your customer service they say phone store or ask online...

So who actually know whats going on? Who is going to refund my Ucount?
