Absa poor service

I have 2 credit cards that I no longer use. I am just paying them. I do not receive any statements so I am paying what I think I should. Absa has now appointed a company name Strauss Daily to stalk me. They phone 20 times a day to say I own money. The only thing I ask is to receive proper statements so that I know what is going on in these accounts. Not to much to ask I think. When I explain this to the gentlemen phoning me from Strauss Daily he tells me I need to be educated. I am an elderly lady and I refuse to speak to rude people like this. Absa stop this company from harassing me. I am no ***** that wants to run off without paying. I only need proper statements. I WILL NOT deal with Straus Daily.
