Pathetic service

Ordered blinds from Blackheath Interiors on the 21/10/2015 and was told that they would be ready in 2-3 weeks, At end of week 4, I called and left 3 messages requesting an update and none of my calls were returned. When i went into the shop, the manufacturer was blamed for the blinds not being ready and no explanation was provided for my calls not being returned. I was promised an update on the following day but no communication was received. The blinds were installed the following week but one of them was too wide, as the slats on my bay window overlapped and the proposed solution...open one blind at a time. When I expressed my disgust at this, I was promised that they would return to \resize"the blinds. Upon their return"
