Unexplained Cancelation of Contact Number

Last week my sim card and contact number ********** was suspended and then canceled by Telkom. Apparently I received ********** airtime, however I do not recall purchasing or activating airtime that wasn't through an authorized prepaid system. I've been talking to agents in store and over the phone to rectify this however there seems to be no clear indication as to where, who or what transferred this airtime that is claimed to be **********. They cannot even tell me who suspended my sim card or my number as I am trying to make direct contact with them to trace this "**********" activity. Its been a week trying to solve this, it has cost me dearly as I run my business through this number and all my clients aren't able to contact me. For the last 7 days I have lost four clients due to the fact I was unreachable. I fully hold Telkom accountable for this, as they haven't done anything urgently to assist me after I told them the importance of the number they have just Canceled. I even reached out today still no progess. I am utterly appalled and fuming with frustration! This has proved that Telkom is poor as a service provider, poor with customer service and disgustingly unprofessional with the inability to service the needs of their consumers. I will be forwarding this to the ombudsman if this matter doesn't get resolved. I need my number back so I can port it back to Cell C as it doesn't originate from Telkom.
