Appalling Unprofessional Service

Since the demerger from Investec their credibility has dropped to -0. I am in process of investing quite a large sum with them, but over the past few weeks the service has been ********** to say the least. To save myself unnecessary frustration in the future I rather Invest elsewhere. I seems to me that they are deliberately giving customers the run around. Are they perhaps in trouble and not disclosing it?
