Still battling to obtain some service

It is now nearly 6 weeks since I requested Plankton to provide me with a refund for the amount left on my card (a thousand odd rand). <br> <br> After numerous phone calls to Plankton's Customer Support line, I have yet to receive any service from this company. The operator that took my calls advised that one Karli is the only person who could assist me in this regard, but Karli was never available to take any of my calls, hence a message was left with EVERY call for her to phone back. <br> <br> After a few days of calling had rendered no results, the Operator provided me with her email address. After sending Karli an email with all the necessary details and still no response, I sent an email to all the email addresses listed on Plankton's website, requesting them to advise whom I could contact to obtain some service. Subsequently I was provided with her cellphone number.<br> <br> I phoned Karli, she was of absolutely no help, giving me some irrelevant reason for not attending to my initial refund request. I have to phone from a different number every time I call, otherwise my calls are screened.<br> <br> I have ran out of numbers to phone from, hence this post. COULD SOMEONE PLEASE ASSIST !!??
