*****ing money from people during lockdown!!!

I arrived in South Africa on March 15 and rented a car from Budget till 2nd of April. Before lockdown i extended my rental and paid in full till the 14th of April. After the lockdown when I followed up on the situation i was told every customer will get charged R50 a day till after lockdown even if you dont use your car and you not alloewed to take your car back. Im getting charged R50 a day from the 27th of March till end of lockdown? Why if i paid in full till the 14th of April? Should be charged R50 from there onwards? The president states that no business missuse the lockdown period and this is exactly what Budget has done. They dont even respond to any emails i have sent. Why dont they just take the car back? When i asked about why charge me from May 27, she rep**** thats wahat the customers asked for or i can choose to pay the full days rental price if i want. Very arrogant!!!!
