CELLC

Good day , I would like to hear if anyone can assist me to take cellc for investigation. My contract expired in february 2025. I Did write a review here before about cellc , when they contacted me they informed me that i am paying for a 5 GB instead of 1 GB , I never agreed to this , my contract was dubble the ammount after my contract expired. So this company did deduct my money last month, I left it cause just want to get rid of cellc. Then they deducted money again this month May 2025 , I manage to reverse. Can I please get advice where to go so that my case can be investigated. i did not give permission or given a signature to agree for upgrades and overcharge for a contract (which where already paid for) . Please dont want cellc to contact me again , as they just give excuses and different stories.
