Pathetic Service for Commutation of my Annuity

Sent an email for my Annuity to be commutated on the 28th of December 2020. Since then it has been a roller coaster ride. From being told my documents are outstanding and being told there is a form i need to complete whereas from inception i made myself clear about wanting to cancel my annuity. They could have just forwarded me all the documents i needed to complete for this to happen. Well, as if it only ends there, but this was just the beginning of my misery. Mind you, i have sent through my ID Copy, my Marriage Certificate and my Notice of Registration from SARS. I have been calling their call centre ever since and every time i do, i keep being promised that they are working on my case and that feedback will be given soon. At some point i was even promised an immediate payment. I can assure you that till now, no payment has been released. Now i am being sent from pillar to post regarding my Tax number of which they say its invalid when they try to send a Tax Directive to SARS. I then took it upon myself and went to the SARS offices and was told there is no such. Either the person who is trying to submit is probably capturing wrong information. Then i called Momentum again to tell them about this and that they should verify if my details are processed correctly on their side. To my surprise i then realised that my ID number is captured correctly however, my Date of Birth is incorrect. I mean how pathetic is this! I also learned that they still are using My ****en surname instead of my current surname though i submitted all documents to make sure that on their side they are able to change whatever information that does not correspond to the documents I have provided them with. Its been a race ever since and i seem not to be getting to the finish line. Every time i call them to check if this has been corrected to enable them to send a Tax Directive so that i can then get my payment, i still get sent still from pillar to post. I was then told they need to change my details first on their system so that they can send a Tax Directive. Even with that, to change my profile seems to be the hardest thing to do on their side. This is still not sorted! I mean really, how many calls must one make to get this sorted. The service received is pathetic. I constantly need to follow up and still no progress is made with this. I really am dissapointed and was not expecting such treatment from a reputable company such as Momentum. Guess what??? No changes to my profile, No tax directive has been sent to SARS. A month later, i am still battling to get the payout. I am really not happy!!!!
