useless telkom

I sent this message in 2016 and now in 2018 the same thing is happening again with Telkom

this time they want to suck R1000 from me

i have a contract with telkom for 1gig at R99

the guy that help me sign the contract did expalin everything to me so on the firts months i end up paying R840 , when i call the call center they say i was surposed to cancle my spent limit , i asked them how their say its fine the will do it for me .

i just got my next invoice now and i must pay R599 .

i went to the shop yesterday and ask them how come because you said it will be solved.
