ignorance

I have ordered and received blinds at Decorland in Games stores Clearwater. The cord broke and they said they'll make a new one and when ready I can bring the broken blinds to replace. then I received an email that they will only repair and I must bring it in. their preferred installer Richard was blamed that he did not install correctly. on what grounds do they make this decision after we agreed as above. Now since Feb 2020 and COVID and no help from Decorland till date 25th May 2020 I plead help. I cannot take blinds off and Installer wants to charge me petrol and labour to remove and or repair with costs - I'm an old woman and Decorland is changing their story and ignore my emails. The problem does not get solved - it has already been months that I sit with the broken blinds
