STILL AWAITING A RESPONSE AND MY REFUND 90 DAYS

I lodged a previous complaint on Sat 31 Jan 15, and I had a very good response from by means of 3 calls from ***7 which were all very professional and I had GREAT EXPECTATION. The calls came at 10:37, 11:35 and at 12:07 in which I informed Arthur. 5 Feb I receive an sms from Ashton to tell me he'll keep me informed. Today 9 Feb NOTHING!! I then mail Silindile at retentions requesting a copy of the last invoice dated 3 Jan 15 which he/she eventually does after numerous emails. I then notice that VODACOM is CHARGING ME FOR THINGS I ALREADY PAID ON 11 DEC14. I bring this to SILINDILE'S ATTENTION via email requesting a full refund including interest back dated to Jan 15 as they had no right to the last deduction of R1207.70 they made. If any money owed to them at all, it would be the last calls of R446.98. According to Arthur this matter was escalated and once the refund would reflect in THE VODACOM ACCOUNT, only then would I be refunded, which could take anything between 7 to 10 working days, it has now been 60 days (more or less) and no response AT ALL FROM VODACOM!!! SILINDILE at Retentions/Cancellations as well as Arthur ***7 AND VODACOM YOU HAVE FAILED ME!!!
