Phantom billing

I logged billing query at Telkom store and was called by Sam from your billing dept.<br> <br> A voice bundle R25 was added to my num and a data bundle R29 to my fiance's and will be deducted this month.<br> He reckons the purchases were done via USSD, but I never use the USSD service.<br> <br> Firstly, because we have unlimited data on our contracts until end of march, secondly, my voice mins are never depleted as I hardly call other nets. It carries over every month.<br> <br> I asked how this could happen and the best answer he could give was that someone probably used my phone to do the purchases.<br> That doesn't make any sense. Use my handset to buy me voice or data??? Also my phone cannot be unlocked by anyone but myself as it has a fingerprint reader.<br> <br> I am tired of battling Telkom every single month since I upgrading late 2015, wasting my time with billing, data and debit order disputes, having to visit the bank and queue repeatedly due to Telkom's negligence, also the bank charges incurred. Then resort to this medium for assistance.<br> All to find it was your error then it gets corrected.<br> And if I ddnt scrutinize my bill every month?<br> <br> I've had enough, fix this or you will be hearing from the ombudsman.
