Disgusting service provider

What a nightmare trying to sort out a problem with this company. They've deducted an amount of R16780. 00 instead of R4195. 00. As pensioners we definitely cannot afford this, our other debit orders will no be honored because our account is in the red!!. Contacted their offices on 6 occasions, held on for 30+minutes, 20+minutes, 15+ minutes and my calls were dropped. Promises of call backs, never happened. All this even after I contacted them after receiving an sms informing me that an amount of R8390 will be deducted on 1st October, again promised that they will be deducting our normal amount of R4195.!!! ×instead they doubled the amount of R8390. Useless call center. Don't know what we going to do for the rest of this month, no money,they don't seem to care.
