Disappointed and frustrated

I had defaulted on my Vodacom account and I made payment arrangements on my account. Once I had money available I made the payment and I was told my account would be reactivated, I paid just over R4800 to bring the account up to date… my cellphone line was never reactivated and now they say I owe another R3800 and then today I just received another message stating I owe an extra R1900 - how on earth am I expected to pay such ridiculous amounts in a space of 4 months.. I’ve been calling and trying to fix this but no joy from Vodacom… I keep speaking to *********** advisors who just can’t seem to understand simple English
