Poor claims experience with 10x Investments

I contacted the 10x call center on the 4th of March to find out if my claim for my pension had been finalised and was advised that by 8th of March the process will be completed. When I followed up today, I was informed that 10x still has to apply for a tax directive. 10x sent an email to me on the 14th Feb stating that all documentation had been received,the last contribution had been invested that a tax directive would be app**** for and this has not happened up until now? A timeline of 14 working days lapsed last week which was the period set by 10x for the claim to be finalised and still this is still not done. At no point did anyone contact me from 10x to advise that the timelines provided will not be meet, and I feel this shows a lack of customer service and incompetence by 10x. I will never invest with organisation ever again!
