Poor service and lack of agency

I submitted my withdrawal prior to the 4th of Aug 2022 with Momentum (fundsAtWork) and called on the 8th to ensure that all the paper work is in order. I was told my claim has been submitted on the 4th of Aug 22 and it should be resolved in 10 working days... To my surprise when i call to follow up on the 18th of Aug i was told that only then it was submitted for disinvestment i still need to wait for another 5 working days. So basically if i didnt call it was not going to be done and now i am being inconvenienced. Very Poor service from momentum and no one know who i spoke to prior the 18th and 19th of Aug and i was promised to be called back in few minutes. now its over 48hrs still no call back.
