Telkom abnormal debits

<p>Took out a mini-router contract with telkom with 5gig day 10gig night surfer deal and pay R149 p/m in February in TygerValley shopping center. In march they debited 798 bounced because I had less (R500) in my account, went to the store was told I exceeded the limit. I asked them to make it 5gig day and 10gig night so I can pay 149pm. But on 25april R 1647.96 was debited please take the amount you suppose to take because I need that money.</p>
