Bad service/ refusal to cancel new contract

Around January 2026, I app**** for a new contract inwhich after three weeks was told the device was not in store anymore and made another new contract which was supposed to come with sim card and smart watch. It took a week and half not coming then called again and again another contract made and when I enquired about the abnormal payment shown on bank payment mandate the consultant just dropped the call. I even wrote a complaint to cell c regarding that which was never rep**** . The phone was just send to me on 02 FEBRUARY 2026 without sim card and smart watch, because I struggled on that contract I decided to return the phone on 06 FEBRUARY 2026, and made a call on the 11 February 2026 and was given CCD number and told phone is on last step of inspection will automatically be canceled I don't need to call again. On the 12th FEBRUARY 2026 was called to make an upgrade which was due that's when I discovered the contract is not canceled, was referred to retention department and was told the case has been escalated. Again on the 02 March 2026 took a contract of data of R299 which is for 24 months and discovered that the contract is still not canceled. Was referred to retention department and told the matter is escalated. On the 06 March 2026 called retention department again now give Ref No.*** which was canceled on 09 March 2026 with allegations that I failed security checks. On 10 March 2026 another case escalation made with no hope of success of contract cancelation as was told will be called again
