Pathetic Service and Communication

I am utterly disgusted with Wesbank and their collections agency 'Collections Solutions'. I receive an email on 19 April 2016 telling me my account is in arrears. a payment that had not been processed in September 2015 (8 months) later and i receive an email on 19 April 2016. When inquiring the matter the very same day I was told that the collection company had my email all along but there was no other communication sent except the email received on 19 April 2016. My credit worthiness has been affected due to the complete lack of communication and the sheer lack of service. Due to their inability to run their operations correctly i have now received a negative credit rating. I have been with Wesbank for 5 years now and the best believe that once my term is complete with them I will not make use of them again and I will also advise others that I know against using them because they cannot maintain clientele in a manner such as this. The absolute shocking service I received from their collections department was even more astounding. I am utterly disgusted in this and expect that Wesbank ensure my credit rating is not affected by their complete lack of communication
