Deleted number without consent

I experienced the most horrible service from vodacom-Call centre this morning, to such an extent where the call centre Manager by the name of Zoli hung up my call. I have a contract with Vodacom, which I use solely for business. Apparently the account went into arrears of which I was not aware as the last time I spoke to them I activated a debit order. I phone this morning to find out why my line is dead and I was notified is deleted and there's nothing I can do, He told me he sent the smses which I never received. All I wanted was my to activate the line of which I owned the number for over 10 years but he told me its none of his business. For a secon I thought I was in the banana republic. I am horrified by this!
