So Disappointed with Truworths

I’m so disappointed with Truworths I paid on January the on February I was in hospital account was handed over to MBD they called me and I made arrangements with them that I will pay R920 on the 13 March 2020 as I’m not longer getting paid on month I’m getting paid on the 15th each month.... but evening now after making arrangements with MBD I still get calls from different Agents telling me today I’m no longer going to pay R920 I’m gonna pay R950 the other one called me earlier today said outstanding money is 1000 and something I don’t know why Can’t they wait till 13 th Friday and see if I’m gonna pay I think I made a mistake by opening Truworths account I regret it these people call even over hours
