Very much dissapointed 🥹🥹🥹💔💔💔💔

I've been asked to pay for subscriptions that I dont know off, my Sim card is on a router but they say I must pay R1600 where by I used to pay R280 now because of that I must pay those subscription to the store before my account will be taken aot of areas...is it possible that a Sim that is on the router sign up to the subscription, they say they dont know anything about that yet I have to make a payment of those subscription to the store, like I owe them...the nerve of MTN🥹🥹🥹🥹🥹🥹🥹💔💔💔💔💔 everrytime I call the contact center they tell me they have canceled them but come month end they are back again...I wish I had a lawyer to deal with this matter
