Sky customers, using the firm’s NOW TV box, haven’t been able to buy a Sky Sports Day pass.
This pass usually allows sports fans to get all of Sky’s channels for a one-off price.
Many Man Utd and Man City fans have taken to Twitter to complain about the issues which appears to say “Something’s gone wrong” each time they attempt to buy a pass.
While another simply said: “# nowtv 1hr still no sky pass – what a waste of time!!!”
It’s currently unclear what is causing the issues but it could be that too many people are attempting to buy the Day Pass at the same time.
To make matters worse it appears the game is turning in to a classic, with Man City currently leading their arch-riivals by 2 goals to 1.
Called NOW TV Combo the service allows customers to choose their TV package, broadband speed and phone calls without ever having to sign up to a contract.
Sky says Combo users can cancel or tweak their package at anytime.
This means you can speed up your broadband, add channels or get free calls at the weekends by paying a bit extra each month.
But, if times get tough, you can just as easily remove certain services or slow your broadband back to basic speeds.
A standard package which includes basic broadband, pay-as-you-go calls and Sky’s entertainment TV will start from £9.99 per month plus a monthly line rental charge of around £17.
