Cellphon contract

I took an cellphone contract at incredible connection store on the 16th of August 2022 an IPhone 13 that was on promotion.i did specify that a debit order should be made on the 25th of each month of which its the day am getting paid. Come September no debt went through then I made a call on the 30th to find out wats going on the agent I spoke to told me to go back at the vodacom shop to rectify that of which I fail to understand why she couldn't do that over the phone or transfer the call to finance department. Went to the branch in springs mall and the guy told me they won't be able to help only the call center can assist with such. One of the colleague overheard the conversation then he said maybe I should go to incredible connection to check with them regarding the contract which date did I sign up for a debit order. Got to incredible connection store explain everything and the manager told me unfortunately they only sign up contracts they won't be able to assist.. what a waste of my time 😒 running around as if am the one who is on Fault here!!! Made a call Again to vodacom call centre hence no money is being debited yet so on the 5th of Oct 2022 finally got an assistant from agent and explained whats going on so apparently the contract specified the money must be debited on the 1st of each month 😒 but then I only get paid on the 25th why 1st?? And even if I agreed on the 1st why still no debit other going through, so guy apologized and he promised to rectify the date . So now I am behind with two installment and I told the guy I won't be able to pay that amount hence work on budget and its not my fault that the money was not debited on the day I requested but because I don't want to see my name on bad credit record I agreed that the amount must be divided in two installment instead of paying R3500 in one payment I can only afford R1700 for this month . To my surprise nothing has been done!!! No money was deducted again this month of October. We are in 1st of November today since I've taken the contract on the 16 of August no money is been deducting are u really guys expecting me to pay such huge amount of which its not even in my monthly budget??? I am not gonna pay any extra money or any late penalties 🙄 can u guys fix this contract or must I take the phone back to the shop co really I fail to understand whats going on
