Total Debt amount payable increased after 1 1/2year's + payments???

I've been with Debt Rescue since march 2019 when my total debt was just about 160K... honoring all payments fully for about a year and a half + till the covid 19 hard lock down came into working where I had a salary cut and 17.3 forms were submitted and approved after sending you guys all the relative supporting documentation from my employer etc. My current outstanding balance on to these creditors are now 170K?. How is this even possible?. I've sent an email to your offices on Tuesday which is now more than 48 hours later and I've had absolutely no response.
