Telkom

I have a problem with Telkom last year I took an upgrade coz the other account was coming to an end, everything was OK then on Feb I took an upgrade again coz the other phone was coming to end and all the agents who were assisting me assured that everything is. The following month a stated getting SMS with case number I didn't understand wat was that for coz Telkom never communicate with me unless they want me to take another phone. Last Month May one morning when I woke up got an SMS telling me that my services are block then I called them wanting to understand why, I spoke to one agent and she told me that when I was doing an upgrade there an amount that I hade to pay and I asked why was I not told and why didn't add it on the first payment she never gave me a straight answer and told me to go to the store they will be able to give me answers and when I got to the store they were unable to help me and told me to call customers service and did that, I spoke to the second agent then he told me that when he looks in the system I'm owing Telkom R8900 something and I ask him how coz I was paying my accounts well how possible is that then he told me that something happened when I was upgrading to honor 200 lite the phone that I took on 2022 which is an honor X8 it's a 36month contact I was shocked coz that phone it was a 24month contact and I was R329 for it and I took it at the store at Ferndale even now my Sim cards are blocked I'm not getting any help every agent that I talk with is just giving a around around I don't even know who to talk cause they keep on telling me that they will call me after 72hr but they never come back to me they just open the lines when it's towards month end they close the lines after 2weeks I really need help with this
