Disappearing data by TELCOM

Data is just deducted by TELCOM for no reason. Their customer care number 081180 is inaccessible. How do I recover my money please? Times are hard for everyone. Yesterday 24/ 10, I bought R10 . When I wanted to convert it to data R6 had been deducted. I had not borrowed anything. The previous day, I also bought R10 airtime. When I tried to convert it to data T4 had been deducted. I am tired of these disappearing data games. TELCOM please replace my data
