Edgars Mobile Content

I am so angry with Edgars Accounts and RMCS. According to Edgars I signed up in May 2015 for this mobile content subscription via Mobile Market. What the hell is that? I would like proof of that supposed contract I signed for. I have never received any airtime and as hard as I try I cannot get any information or help from Edgars themselves. I paid up my account at the end of 2018 and I am continuing to be built. I want this billing reversed. I will have already paid it unknowingly in my previous payments as I just paid the amount due every month without checking the items on the statement - my error I know. But now that I have no longer made any purchases at Edgars for over 6 months I am still being billed and hence my looking into it.
