coaxed in to signing form

Hi Percy Hanto again, Last week Wednesday i received a call from Johannes telling me had been aware of my complain from the management with regards my insurance. In his call we spoke about the unsigned form the insurance had spoken about regarding me taking insurance from the day of an upgrade. Johannes said he will call the insurance to be sure of what they are talking about clearly. after the call he sent me a form that was dated 06.06.2020 with his signature attached in it. i have all communications with him through emails since it was the only form of communication we had due distance. i called him and asked if this date was really legit if i put my signature in it and the experience was devastating since he told me he had sent me forms and he is busy with other customers. To pay MTN billings and having to endure such things is hurtful cause i pay every month. the next day Thursday i called Mtn Insurance and the lady who was assisting me, I explained to her about my 717128 ticked ID and the dated form and she asked me to send it... and that was to confirm if its okay to send it since Johannes was not the same guy anymore and i was avoiding altercations with him, in the middle of my phone call he called me again but the lady had already assisted me then that time Johannes sent me an email of a form that is dated 07.06.2019 and did not explain anything but asked me to sign it and send it to insurance, He was never even transparent about it, i cause trusted this could help me with the burden of not having my device and accessing my personal email from University singed it and sent it to MTN insurance and than got a ticket ID 545324 only to find out that signing that form Johannes coaxed me into lifting the burden off him, cause i made a phone call and the insurance lady for the second time told me that they can only assist me or rather process my claim under the conditions of me having to back pay all the months from last year July till this year July or if i agree to terms that cancel my previous device policy and they put on the newer policy for my recent device and did me fees differences and that amounted to 980+ that i have to pay. guys if i am a loyal paying customer and i have never given mtn any form missing my payments but enduring all these how will i believe there is any customer service between me and MTN when i left the store knowing my device is under insurance? how is it customer service if this is an internal error ? and this proves i am right cause Johannes sent me a wrong dated form to coax me into signing the paper by lifting off the burden for him after realizing his mistake. i have been paying insurance since i picked up the device from 960 last year to this year to paying 850 but i am only told this year my device is not insured and that i have to set agreements and also do payments. mtn has never provided a good service since my claim, mtn has never been fair to me since my claim, because if you render a service and am not happy about it i have every right to not pay for that service. When will i even get my device back so that i would pay your bills perfectly too?
