Cell C review: Number porting and integrading my prepaid with a contract

1st i was advised by the Contract Holder Mrs, A Heyns that i should change my Service provider from Vodacom which i have been with for 15+ years, so we went to Cell C Highveld mall and they assisted promptly with the number port and everything went well, after that we requested the cellphone number be integrated with Mrs. A Heyns contract since her husband passed and she no longer uses the benefits of the contract. after that we have been struggling to get my now Cell C number integrated with her husbands contract after about struggling 3 weeks mrs. A Heyns went to the Highveld Mall branch and they assisted in the process i they deleted my number from the network and gave me a new number, keep in mind when i did the number port from Vodacom to Cell C my only concern was loosing my number as i have had this number for 15+ odd years. Mrs. Heyns asked me to contact her and then we came to know that my number has changed. throughout this whole process never once was i called nor informed that my number is about to change or that they requested my ID number to gain access to my number or nothing yet the consultant managed to delete my number off the system and network and managed to get me a brand new number all without my consent. Then she ha the nerve in saying to Mrs. Heyns that, that happens sometimes, after i asked for my number no changing she did it any way. With this being said i am lodging a formal complaint of incompetency and the consultant not knowing or informing about the problems that might arise when doing certain actions. now i need to take my time in changing my number at my banks, at work, at my contracts i have with various big companies such as Mercedes-Benz South-Africa and vendor lists all because of a consultant and a company not knowing what they do. Who will be compensating for this time spent on someone else's actions.
