Impossible service

I recently upgraded to private clients and was told to call towards the end of May to upgrade to private wealth, I've now called 3 times and was promised 3 call backs with nobody ever calling me. I called in 3 times this morning went through the options was told to hold only to have the call dropped each time and nobody bothered to call back. I would like to get this done asap but at this rate it seems it's never going to happen, can someone please call me to do this upgrade this morning.
