Misleading

I'm very upset with game they show they have things online but after you have paid then they want to cancel the items and tell you that they don't have have stock and the email they sent said that I have to wait 3-5days for a refund afterwards when I reached our in which no-one has ever reached out to say why it's being canceled where as they still have stock online they telling me I have to wait 7-14business days which is basically a full month. I'm so furious because where does one get money this time of the year to go and purchase a other pool cover they only come with sorry but no solutions what so ever. Why can't they go an find the items in other stores and have it sent its just sorry, I asked why couldn't they give me options come in store we will give you a voucher or give me options of alternative items and it's the pillows and the pool cover this is very misleading because when I go online now it shows that there is still stock left.
