price was incorrect

Bought ironing board price on item 89.99 at the till price 199.99 ask for manager as nowhere was there price of 199.99 he explained that price 89.99 was for smaller board but I showed there was no other price on their even the two cashiers assisted me but she just took off the board of my purchase and said theres nothing they could. I ask about policy about price u see is price u paid. I was told they cannot give to me at the price 89.99. And left. This happend 16/1/16. I would like to be honoured it was there mistake. I worked In retail a long time and if price was wrong I had to give to cust at that price. And should really work on their people skills.
