SHOCKING SERVICE

I purchased a photobook voucher from Hyperli. The instructions were to download the programme and then create your photobook. I was unable to download this programme at work as it was blocked by our server and unfortunately I do no have Wi-Fi at home so couldn't download at home. I contacted the supplier(Photobook Factory) to ask for assistance, and they could not assist me at all. Therefore I then requested for this voucher to be cancelled and for Hyperli to give me store credit. I got confirmation that this will be done and that I had to completed a return form, which I did. 2 days later I was told that my voucher was redeemed and they could not action my request....this after I got confirmation that it will be done. So once again I contact Hyperli and advised them that my voucher was not redeemed. I got their automatic reply by email and it says that within 2 days they would get back to me....Then bam....NO RESPONSE AT ALL!!!! You cannot call them as there is no contact details just an email address. Its been 2 weeks and my query has still not been resolved. I work at a finance company whose staff always buys on Hyperli but I will make it my mission to tell all my colleagues including friends and acquintances to never ever support Hyperli as they clearly have no idea on customer service!!!!!DISGUSTED BY THE LACK OF SERVICE!!!
