Account Cancelled without my knowledge

Last week I called Telkom mobile to find out when I was due for an upgrade then I was told to go to a Telkom store to do a sim swop because my account was suspened. I went tothe Telkom store then I was told they needed to log a call to do that. Now Im being told that I no longer have a contract with Telkom... I would like my credit on the Telkom account to be refunded to my fnb bank account ASAP.
