Holding deposit, interest and information

After renting from the above for nearly 13 years Mr Martin stated that my interest on my deposit of R3800 supposedly in a 32 day call account gives me interest of R6.49. I have approached him on numerous occasions, emails and calls regarding the matter and he has pitched a whole lot of lies. I have proof of all the emails and i can forward them to you if need be. I really need your help regarding the matter as Mr Martin is not coming to the party and keeps making excuses and blaming ABSA bank. I look forward to hearing from you, thanking you kindly EM Jordaan.
