double charged for an online purchase

<p>I recently bought groceries and food at woolworths online. Immediately after the purchase an amount of R1223.12 was deducted from my account, this amount was for all the goods purchased. I then received an email informing me that my order will be split into three deliveries and will be delivered. I received the order on the scheduled time and was very happy as everything was there. To my surprise after I have received my order, an amount of R134 was deducted from my account as a purchase from woolworths. On saturday another amount of R254 was deducted, again as a purchase from woolworths. Then on sunday an amopunt of R823 was deducted from woolworths. I do not seem understand why this is happening because these amounts are for the purchase I had made which was immediately deducted after my purchase. This now means that I have paid double the amount o my order. This was my very first time shopping on woolworths online. I am afraid I m not gonna shop online again if it means being double charged for your goods. </p>
