Bas service from Vodacom legal

Sykom attorneys have been instructed by Vodacom to collect money for a contract I settled through VVM attroneys in May 2015. I have sent the settlemtn letter from VVM and proof of payment to Sykom to show that the account is paid up.<br> I also called Vodacom 4 times today to check if I am indeed owing them as per Sykom attorneys. Each time I called I went from one agent to to the next, a few times being cut - not sure if they are having technical issuues or if they are hanging up on me.The last lady I spoke to confirmed that no amount shows as owing under my contract on their system but for some reason she could not confirm that to me in writing. She kept on reffering me back to Sykom attorneys to ask for a settlement letter. I cannot ask Sykom attorneys for a settlelment letter for a matter settled with VVM attorneys in May. I insisted on speaking to a supervisor to get proof in writing that I do not owe Vodacom. She started liasing with her supervisor who insisted that I liaise with Sykom. I assume she eventually got tired of running between her supervisor and myself and hung up the call!!! I unfortunately accont remember the name, but it was an African lady - a tswana/sesotho name.
