Invalid contract

Hi Vodacom customer service I am so disappointed with your dishonest fiber sales team I dealt with two of your agent's,one was at my residents at Route 82 security village 1 Alveda Kibler park I cannot recall his name but I told him that I want a month to month contract and we agreed and signed the documents but he wanted me to send him my KYC documents via what's app and I refused as I requested for his work email which he did not provide .So I then called in a to the sales call center to reapply and I spoke to an agent I think on the 17th of October 2022 and I also told him or her that I want a month to month contract and I was advised that should I decide to cancel I will pay R135 for a period of twelve months for the router which I was happy with , yesterday I spoke to Yamkela from service support who confirmed that I signed a contract for 24 months and that I will be paying an amount of R690 premium after the first four months.I then requested for the initial telephonic recording of the day I called in ,she transferred me to the sales division were she confirmed that I will get assistance.Zinhle answered the call and refered me to the billing department that's were I spoke to Bongiwe and Shoneye who confirmed that they cannot assist me but they will put me through to the relevant division but then the transferred call get cut or dropped which was a frustrating experience on my end ,my question is is this how you treat your customers once you have secured the deal? I want you guys to please send me the telephone record to my email address listed on your systems and investigate this so called agreement.I would appreciate a prompt response to this issue .My unit number is 402 ,cell phone number is ***.
