CELL C BAD SERVICE

I signed up for An LTE Sim card deal on a Promotion for R289 50GB sometime in February 2019 . I was signed up by your field sales agent Kauthar Suliaman whom advised me that would be the cost im paying . I signed the contract which clearly states R289 For 50GB Of data . I received my first debit of R199 For the sim card which i was not informed of . the sim card was dropped off by me and was activated almost 2 weeks after . i then received my first invoice of R1300 . I contacted your call centre several times regarding my incorrect debits put on my account and spoke to several supervisors as managers are never available to take my call . i spoke to Busi in the customer service division which was the supervisor on duty . she promised to fix my billing for me and promised me numerous callbacks which also never happened .i spoke to another supervisor whom i dont remember . i sent a copy of my contract to them as well and nothing happened with that . i went to the n1 city cape town branch and dealt with Carmelita Marcus whom also promised me to correct my billing as they have a contract on their side uploaded on their system of R700 Pm which was not signed by me . i sent her my copy of my contract as well . after numerous emails and phone calls i still didn't get any feedback , i advised that i will not be paying for the package as i didn't sign for that and will not pay the service until my billing is sorted out . today months later its still not fixed and was given multiple promises regarding my complaints and endless calls to the call center . the service is now not working and im happy to cancel everything as its been a horrible nightmare . Cell C is the worst company ive ever dealt with . You not living by your brand . i expect a response from you guys asap!!!!
