I bought a voucher for three courses and a drink at any of the following restaurants - zizzi, ask, bella italia. I went to Zizzi and tried to use the voucher, however was told it had already been redeemed. (I had already emailed buyagift and Zizzi before going to check this). As we were with two small children and to save embarrassment i purchased another voucher off buyagift - both vouchers were £30 on the website but with a discount code i got them for £20 each. I was then told by Zizzi that this voucher was also not going to be accepted. The manager sat on my phone for about half an hour tryign to sort it out but kept saying it is not valid at Zizzi (even though it clearly states that the taste of Italy voucher is valid at Prezzo, Bella Italia and Zizzi) I was so embarrassed and just wanted to get out of there, two young 5 years olds bored and messing around - was an absolute nightmare. In the end the manager said we have to pay £30. i explained that this is not fair and he could see that i had just paid £20 for the voucher as he watched me purchase it. Now buyagift are refusing to give me the refund. I've bought many vouchers from buyagift for many different things but now im too worried this will happen again. Its sneaky to let you buy a voucher off them and the restaurant declines it making you pay full price - bit of a scam.
