MTN *********** or *****’s.. you decide.. maybe both

On 27 May 2021 Iwas charged an amount of R21 190.84 incl VAT for an early upgrade which I should not have been charged for. It took me 3 months , 72 emails and I have no idea how many calls to eventually get them to pass the credit. However, the retentions department only instructed their accounts to pass an amount of R18 426.81 which is the amount excluding VAT. To date many emails later and countless calls I have had no success in getting the balance of R2944.03 still due credited. Every consultant I speak to agrees it’s due and promises to escalate the query but nothing happens.
