Highly irate with service due to migration from Al

On Sunday, 13/03 my cell phone went dead and as I was travelling my family were frantic as they couldn't get hold of me - on the 14/03 called Altech who advised that all was well on their side and Cell C were to blame due to the migration - I called Cell C and I was not on their database. Went onto Altech's website and logged a query later that afternoon I received an email saying my query was resolved. Today is 15/03 17h30 and I still am unable to use my cellphone - on calling both Altech and Cell C the one blamed the other however I insisted I be helped so this woman called Sunera (***) said she would check and come back to me and this was at 08h30 this morning. I have a good mind to cancel this contract as I am sick and tired of this disgusting service. Was told by Altech that the migration was resolved on the 13/03 - I have lost business, been inconvenienced in so many ways but this means nothing to these 2 useless companies.
