What is this money for???????????????????????????

<p>I just called Telkom mobile now and i spoke to Slindo. I asked her why is telkom invoicing me again whereas my account has been converted to prepaid. My contract ended March 2017. The invoice i received had a total amount of R 1,644.40 of which i had already paid R 1,492.10 in June. So the difference between the two amounts if R152.30 and i dont understand why i owe you this money......I AM SICK AND TIRED OF U TELKOM with your stupid amounts. Like why are you invoicing me? You better have a good explanation of this or else???????????????????????????????????????????????????????? Ndanele finish nini, lonto niyayithanda imali. Asoze ndithi abantu bayithathe icontract kuni ngoba ningamasela. </p> <p> </p>
