I have used Woolmans in years gone by without issue but I have had your experience with other companies. If you paid by credit card you might want to talk to your issuer as you have certain rights as a consumer but you have to talk to them rather than the company you are buying from.
Can I ask if the plants were in bad condition? It's possible that Woolmans use other companies for dispatching. Not all companies use sales, nursery and dispatch through the same place/infrastructure. But yes, they should have been clearer. I like Sarah Raven, but I have had the same thing this year; and Suttons, Jacksons, Middletons and others - big delays. Luckily I haven't beenin a rush. I have just received some shunted begonias and petunias that I ordered in April.
I think it's been a difficult year, cold spring, then staff problems due to people off work isolating. You can't pick and pack plants from home. Sarah Raven told me their grower had had a crop failure with their Verbena bonariensis and they weren't sure when or whether they'd be able to get more, so I cancelled that part of my order. I only found this out when I phoned them to find out where they were though, goodness knows how long it would've been if I'd just waited.
