Do not arrive on time or phone you to advise

Asked Windowvert for a quotation in February. The person arrived on 23/2 and I pointed out the two kitchen windows, dining room window, lounge sliding door and bathroom window to measure for blinds. No quotation received, enquired about quotation on-line on 3/3. Received an e-mail from Michelle Ellis saying the quotation had been sent on 25/2 but the quotation was resent and I received it but it only had one kitchen window and I asked them to re-quote, they then informed me that they would have come and take measurements again as only one kitchen window had been measured. Re-measured on 5/3 and sent a revised quotation. I didn't check the revised quotation carefully enough and paid the deposit and asked them to proceed with the order. They arranged to install the blind at 09h00 on 24/2, when they didn't arrive at 09h00 I phoned the office and was told that they had gone somewhere else first. I had to phone them to find this out, no one had the decency to phone me and inform me that they were going to be late, they eventually arrived after 12h00 - didn't have one blind and the diningroom blind is wrong. Other blinds installed 24/4 - did not arrive on time or phone to advise.
