LOST MY CELL NUMBER

I went to Telkom Shop Wonderpark Shop Centre to upgrade my contract in Feb 16. I had a Vodacom number for 2 years on contract at Telkom ***) No problem from the beginning. Now with the upgrade the guy just needs to do sim swop again, there start all my problems. 3 weeks later and yesterday they said they do not know what they done but now the blame Vodacom and said they discontinued my number. This is a business number I had for over 22 years. Now I am loosing business and also I cannot do any banking because of sms notification that cannot reach me. Got all my correspondence for last 2 weeks between Telkom and myself, they are just not interested to help me solve the problem they cause in the first place. I am desperate I also got dead in the family and no one can get hold of me. Last night someone refer me you your service my last hope before I will end up in a mad house. I ask Beeld for support no luck at all.
