MOBICRED IS A ****. ********* BEHAVIOR!!!

I am appauled at the by the lack of professionalism from Mobicred, i have been paying my account on a month to month basis and i am paying more than the required monthly instalment yet i keep receiving calls from Anthony Richards & associates saying Mobicred handed me over to them and i have not paid my account since last year June and that my balance is R4 800. When i call Mobicred to enquire about this they confirmed that no my account is up to date as per the monthly statements that i receive from them and they also confirmed that i have been paying way more than the required monthly installment so they do not know why Anthony Richards & associates is calling me. I am very disappointed in Mobicred and have decided to escalate the matter with the credit bureau because this has been affecting my credit score since last year June without me noticing and when i check my credit profile i see that the amount that reflects on my profile as a bad payer is the same very amount that this debt collection company claims I am owing.. this is so ridiculous and unprofessional. I would not recommend this creditor to anyone. ****ED OFF.
