Online renewal.....Website error...O sorry now you have to pay more

<p>While renewing my wild card online on the sanpark website the website experienced an error. This error reserved the amount for the renewal three times against my credit card and indicated that the wild card is still not renewed. I contacted the helpline, asking to cancel two of the reserved amounts and to process my renewal on the remaining reserved amount. They then obliged by cancelling all three amounts and indicated that I must fill in a renewal form and email it to them. Ok that's fine....filled in the form and emailed it to Sanparks. Received email back "Please confirm the correct price,as they have increased." Ok so I had renewed my card online on 29 October, got an error on their website, went the manual route and oops no we are in November and the price has increased. This is where Sanparks started loosing my respect. How can you now charge me more because your system isn't working. I then rep**** "I had assumed that I need to pay the same amount that was reserved on my credit card seeing that the website had given an error. I had not realised the fees had changed. However now that I know this I do feel that it would be more ethical to still charge the same amount as the error was on Sanparks side". Their reply "The amount charged on your credit card was applicable until the 31 of Oct as shown on our website and now the new prices have already been loaded on our system. Unfortunately we cannot manually charge this amount because the rates have been updated already. We sincerely apologise for any inconvenience caused." Sigh ok I'll pay the new amount, but still I do feel this is poor customer service from their side.</p>
