Harassment and then unprofessional services

I have been harassed, verbal and emotional abused by Easton Berry Collections. I have been under Debt Review since last year October 2021. This company had the audacity to STILL call me 7.00 AM on a Saturday morning, bombard me with SMS's that I need to pay them and once had an advocate by the name of Mr Mahlasela call me and tried to get me to confess that I owe money! My Debt Review company have already made payments to them 3 times!!! The number he gave me to forward to my Debt Review company was *** there is no answer at this number. Easton Berry Collections also do not answer calls on the following numbers: ***. To top it all off, just today 22 June 2022 - they have already send me 3 SMS's today! How do I stop this nightmare? This is beyond ridicules.
