Eurovision’s ticketing problems have continued after its website experienced technical and payment issues just hours after sales commenced.

The problems came after Concert.ua was reinstated as official ticketing partner just days after controversially being removed from position by Ukraine’s Antimonopoly Committee.

The Eurovision Times fansite reported problems with the website, alleging that some people thought they had purchased tickets after receiving PDF tickets by email, only for their payments to be later rejected.

According to The Register, a spokesman for the organisers blamed the high demand for tickets for some people experiencing problems in purchasing tickets for the event, which will take place in Ukraine in May.

“The EBU urges all fans of the contest to purchase their tickets through this official channel only in order to ensure they are purchasing genuine, valid tickets to the event,” said a spokesperson for the organisers.

Organisers added that a total of 9,384 tickets have already been sold for Eurovision 2017 events.

Pavlo Hrytsak, deputy head of the National Public Television and Radio Company of Ukraine, said that over 70,000 tickets were planned to be sold to nine competition events. Tickets cost between €8 and €500 (£427/$534).
