"They tell me there's a problem with the connection further up the line but they never ever sorted it, and I'm really over being fobbed off."
Mrs Simpson said she was upset that she was losing business every time her Eftpos was down and said she "shouldn't have to be constantly chasing for a solution".
"It's just not acceptable in this day and age," she said.
"I have to say the guys at Spark here in Wairarapa have been very supportive and whenever I go around there with a problem they try to get onto it as soon as they can to support me.
"But, at the end of the day, I can't keep doing this every single time it rains. It's like, oh gosh it's a storm today, it's going to be terrible at work."
Mrs Simpson was hoping that the problem would be fixed for Easter Saturday which is always a busy day.
"One of the owners of Spark has seen the temporary repair that Chorus did last time and he said he can't believe his eyes.
"He sent photos to the Chorus guys and have asked them to urgently get on to it."
The Eftpos was working again after 2pm on Thursday "and that's only because it stopped raining and dried up", Mrs Simpson said.
Her fervent hope was that Easter remain dry -- which it did.
