HomeChoice harassment

I have been struggling for 3 months to get assistance from HomeChoice regarding my account. The company i worked for liquidated n 18 March without telling us. As we went into Lockdown we only found out later. I phoned HomeChoice who requested i send the liquition papers with my id to claim for account insurance. Ive submitted this several times and i also kept paying untill last month. I get harassing phonecalls from HomeChoice and debt collectors up to 5 times a day. I explain the situation over and over. Nobody is able or competent to assist me. I have submitted the documents and phoned them over a over. I phoned again today. After 32 minutes and being put on hold 3 times i put yhe phone down. Now they requested uif documents and a letter of service. I explained over and over the company has not paid over our uif since 2006 and i cant get any documents as they liquidated and no longer exist. This is now not good enough. After 3 months of harassment and submitting documents they requested i am getting nowhere. This is pathetic. My account was always paid and paid more every month for years. Now they refuse to assist me. Today, months after first seeking assistance they only traced one of ny emails I am tired of being harrassed by them
