Vodacom bad service

I bought two tablets about two years ago, this is the second time that my account is in arrears as they stopped deducting, sorted it out again the same thing happens, i should've been done with that contract, now it'll reflect bad on my account. Vodacom is just ****, i was a loyal customer for a very long time before this also had a bad experience. Jy kry *** diens ma julle is verby ***.
