Incorrect contract dates

I have an account with vodacom - *** is my main number, under this number I have other numbers. I called in a month and half ago and got x3 numbers amended. The reason for amending these numbers was that I do not have the devices this numbers and ultimately I want to close them. On my initial contract these numbers were expiring Aug. 2025. The lady who did the migration told me that I do not loose my contract expiring dates. When I received the documents confirming the migration, I noticed some errors and called in, only to find that I am now put on a new contract expiring 2027. I called in immediately and spoke to Lindiwe, who said she will have to change my whole contract and put it back were it was, this process will take a while, she promised to call me back, she didn't, is been 2 weeks now I'm still waiting for her call. I called in today and spoke to Lesego and Zanele, just after I explained my situation to them, both of them dropped the call. Like vodacom has the most *********** stuff members ever. I have never called the call centre and received proper service. I don't ever want to rate them, they are ********, arrogant and just don't care about us. So I'm here with hello Peter, this is the only language that this company understands, hopefully a manager that knows what they are doing will call me and fix my account immediately. I want those numbers closed by Aug 2025 and not 2027.
