I had to get a replacement cooker.I paid for it to be installed and the old one taken away.The technicians from AO.com refused to install it as it did not meet safety standards and took it away.I had to go through the whole process again but this time I had my own engineer so therefore told them I needed a refund as I had already paid £89.98 for a service I didn't receive.After numerous phone calls I am no further forward. Customer Service is a total shambles.Too many people who have no idea what they're saying.I phoned again this morning and the guy said he would put me through to replacements.EXCEPT,they only work from 9-5 Monday to Friday.How did he not know that?Yet they're committed to providing the best service they can.Well if that's the best goodness only knows what the worst is.
