Great Britain captain Judy Murray says she is "fed up" with her team's failure to earn promotion in the Fed Cup.
Britain are in Europe/Africa Group I, and on Saturday lost out in a playoff to Belgium that would have seen them advance to another playoff for a spot in World Group II.
With world No.28 and Australian Open semifinalist Johanna Konta unavailable through injury, and Laura Robson not considered fit enough as she continues her comeback from wrist surgery, responsibility fell to Britain's second-ranked Heather Watson and 16-year-old debutant Katie Swan.
But after comfortably beating South Africa and edging past Georgia to set up the Belgium clash, Swan and Watson were beaten by Ysaline Bonaventure and Alison van Uytvanck respectively to end Great Britain's participation for another year -- leaving Murray "very disappointed".
"All in all, there are lots of things to be pleased about," she told BBC Sport. "But we didn't get out of this zone we have been stuck in for years and I am fed up of it."
Promotion to World Group II would involve home ties for the British team -- something they haven't experienced since 1993.
Murray, who told ESPN in November her plans to make Great Britain a Fed Cup force, added: "You're only as good as the team you can put out on any given year. The last time I was able to put out our strongest team was 2012. Since then, I've always been restricted by illness or injury.
"Next year we want a full team out, get out of the zone into the World Group to have some home and away ties, and really showcase British women's tennis to the fans in Britain."
Meanwhile, International Tennis Federation president David Haggerty says the format of the Fed Cup is under review.
Haggerty, who announced in January that the Davis Cup will undergo a major overhaul, said: "The Fed Cup has benefited from the home-and-away knock-out format that has been so successful in the Davis Cup, and the ITF is looking at new formats that would allow a 16-team World Group, something that is favoured by many of our constituents."
Murray, speaking to Sky Sports, hopes changes will happen sooner rather than later.
"The format doesn't really lend itself to building any momentum for women's team tennis if you play four days in February and then you don't play again until the following February," she said.
