Bad service and communication

In October 2021, I ordered three sets of blinds and they arrived sometime in November. The blinds were beautiful and exactly the style and colour I wanted, but the sizes were incorrect. I contacted Shelley from the company who assured me that they would be happy to assist as some of the alterations would fall under their "Right Fit Guarantee" and a portion would be for my account, which I was happy with. A few days later I got another response from them to say that they could not honour their word and I would be liable for all further costs relating to amendments and shipping. She proceeded to ignore my communication and requests for further assistance. Totally unrelated, but my father passed away during this time as well and I was unable to take it further with them.
