Still no refund after 8 months.

I have moved from 10210 to 081 189 where they insist on a unique code I do not have and none of the Telkom guys are willing to assist. I requested a refund after not receiving the LTE sim card I had ordered even after they deducted 849 from my account on the 14th of January. I was told the refund was logged some time in March and should expect it within 21 working days but still nothing and the consults have the nerve to tell me they cant find my details on the system now since the order was made and cancelled 8 months ago.
