I paid double for renting a suite at dream bride

On the 11th of september I booked and paid R500 cash for a rental for a suite for matric farewell on 29 September. <br> The total cost for the suite rental was R500 with a deposit of R150. I paid R500 cash and the lady said I can pay the R150 when I collect the suite. On the invoice it states still need to pay R150. <br> On the day of collection I had to pay R500 again to get the suite because their system \crashed"and they could not find the payment. I paid it because I needed the suite for the next day and she said we can sort it out when I bring back the suite. <br> When I took the suite back"
