Refund delayed

I am supposed to get a refund from them and they are busy giving me a run around, Logged a complain on the 5th January to PF Centurion and I was told to send the complaint to Head office, then on the 4th of Feb I sent the complaint to the head office where I was called and told they will have a look and should there be a refund due to me they will process, from there no one called I called them back to follow up and was told that the refund was logged on the 11th meaning I will have to wait 15 days, Now today when I called I was told that the matter is with HR and they do not know when my refund will be processed. How so? I asked to speak to the manager and I was told that the manager says he/she has escalated the matter, No ETA I am the one who needs to call them for follow ups they just don't care.
