ABSOLUTELY SHOCKING SEVICE!!!!

Sent through documents to register a COID client on the RMA system. Firstly, was given the wrong email address by a call centre operator so the documents were not dealt with. Upon follow up my email was tracked down and apparently sent through to the right department. Upon not getting any feedback I followed up. Spent close to an hour on the phone to find out that the reason the registration was not completed was due to the documents sent through being for the wrong company. This is appaling as firstly they were ALL for the correct company and secondly I got no feedback to advise that this was the case. I was then assured that this would be sorted out. I then called again the next business day and was asked if I'm aware that the documents sent through were for the wrong company????!!!!!! Pity anyone who has to deal with this company
