EC LOANS unauthorized debit order....theft

My account was debited for the sum of R249.99, this was done *******ly as I never approved a debicheck. I opened a case however my bank does not want to reverse this money. This company is using Sanlam Life Insurance as the collector details and specify a cellphone number which does not exist, Sanlam has referred me to some Multi Data company. From there now sure how many other companies I will be referred to, I am spending more money trying to solve this. EC LOANS.....what gives you the right to ***** from anyone, we work hard for what we have and furthermore R249.99 might seem a little to you but for those who do not have anything that is a lot. RETURN MY MONEY BACK TO ME AND STOP *****ING FROM ME.
