Repetitive Billing

After 6 months struggling with a Vodacom and happily working with the first collection agency, Vodacom eventually passed my credit due. With still pending dispute queries, the account collection was given to MBD Attorneys.<br> <br> I requested MBD to assist with the queries which I still had only for them to request a sworn affidavit, ID copy, etc. for requesting my invoices on my account to ensure that all the billing matters have been credited. Frustrated with this request I just decided to pay according to the amount owed on the official MBD letter.<br> <br> After my payment another letter received stated I owe an additional R 400. This of course frustration, but I again paid the amount from the official MBD letter. I then received another letter now owing R500 and today a letter stating they received the payment but I still owe R200. Apparent costs accumulate from calling, sending letters and interest charges. <br> <br> What protection does the consumer have that these account do not run up to the 1000s or even 10000s. I again made the R200 payment and hope it's the final payment and hopefully now they will just be as quick to charge as reverse any adverse credit affect they impose.
