Tax and Bookkeeping Amasevisi (PTY)LTD - Their service is VERY BAD

I am really dissapointed in the service I got from TBA/Joyfin as I have lost a tender because of Tax non-compliant. I terminated the services with them last year October 2019 and early this year I got an email for a tender which I app**** for sometime in September 2019. Early January 2020 I received an email informing me that I won't be rewarded a contract due to tax non-compliant. I called SARS to clear everything and when I requested my EMP201 & EMP501 I got a decline email informing me that I owe TBA or Joyfin. I cannot explain the hurt that my company suffered in the hands of this company as it is last year I had to submit my returns late because of them and I had to pay penalties and now I lose business because of them.
