TELKOM tries to take refund back

My Telkom saga continues, 6 months and counting. I was refunded an amount for being charged data ********ly for close to 4 years. 2 days after refunding me, Telkom hit me with an invoice for the same amount, about R11,000. I have been ignoring those invoice amounts and just paying my normal subscription fees ie for the package what I signed up for: the landline with ADSL facility and no data. Each month since the dispute was logged (by Maaliek and the excellent team at TELKOM in Rhine Rd,Sea Point), I have been charged for odd costs like service fees, credit and interest on the false amount. My account should be in the region of R650 a month yet this months invoice was over R1000, R300 more than May's invoice and it seems TELKOM is trying to claim back the refund in this manner. It is beyond frustrating and super stressful dealing with what must be one of the most dreadful and poorly run companies in SA. I'm at my wits end. Allison Foat- van der Spuy
