On line chat colleague was utterly incompetent. 4 attempts to get changes made but still didn't get it right - and she was working from the written word! Made a payment on the automated telephone system the next day because the chat colleague said she couldn't take payment. 4 days later I still hadn't heard anything so I called. I had put the ref no. in wrong so the payment wasn't in my file. Why did the system let me pay with the wrong number, why didn't the system let me check the reference number when paying? Used One Call for years but they seem to have gone to pot. One Call? Huh - took me a damn sight more than one call! Useless!
