Duplicate registration paper request gone incognito

I have requested and paid for my duplicate registration papers on 20 March 2025. Up to this day I am still awaiting receipt of my documents. I have spoken their Customer Services division on average twice a week during this time at my own cost and on the line on for at least 30 minutes per call. They promise to phone me back every time. 2 calls received in all these months. Staff talking that was of NO assistance. Every time I phone ALL of them are either in a meeting or not in the office, everyone dodging my calls. I even started using **** names just to get put through to staff that assisted me... then they are not in meetings suddenly. (Apparently everybody is working from home, in a meeting or off sick). NO one wants to put me through to management - K&S after numerous requests and no direct office number given for me to contact them. Their issues with their 3rd party provider - RTMC - is not my problem. BMW finance are quick to take your money and follow-up and take action if anybody does not pay, don't you dare ask one thing from BMW finance and they do not offer any assistance at all.
