Nedbank and harassment!

Due to the economic climate in South Africa and being a single mom at the time I hit on a really rough patch in my life as my business which is a guest house was under strain as business were cutting back on travel and tourism was dwindling... I begged nedbank repeatedly to help me restructure my bond and extend my repayment period to lower the repayment.... They refused repeatedly... I ended up with a loan from direct axis and a loan from my ex husband to try and pay the bond so basically ended up in more financial issues as Nedbank just wouldn't assist me from there I went under debt review and have been since Nov 2019... Nedbank has suddenly in their wisdom decided they are not accepting my debt review and have handed me over to lawyers who harass me daily... And now the nedbank home loans department have issued a summons... But if I'm under debt review and they are receiving payments how can they now decide they don't want too accept the debt review ... Please advise if I have a case against them as I was under the impression that once under debt review then no one can contact me directly as they have its tantamount to harassment...
