Online banking **** involving takealot

Someone is using ***** to buy things online on takealot platform and what is wrong is that there is no easy way to report to takealot which make it look like they are running away from responsibilities. I was ****ed online and on my bank app my R320 was used to purchase at takealot Capetown.. Someone from takealot should contact me to resolve this before I escalate this issues I'm trying to remain calm but I'm hurting
