Slow service! Quick Billing!

I am totally up to my eye***** with frustration!! Elite Mobile's service is unsatisfactory! billing me unreasonably, I want out NOW! yeerrr. They called me on my vodacom number and told me of a deal where they deduct R19 from my bank account & give me R49 airtime I agreed then later advised them to also bill my BIS of R59 so that I don't have to buy at shops. Now all that's changed, I no longer get BIS! After months out of service they tell me of some new wifi thing they will provide while I wait for BIS that has NOT worked out! I don't want it an I don't understand it! All I want is my BIS and stress free life PLEASE!
