ALWAYS INVESTIGATE AN ACCOUNT & NEVER GET AN ANSWE

This is the 2nd time in less than a year I have had an over priced account with Altech. I have been with them for over 13 years now but this WILL be my last contract with them. I received my account & there is an amount of R1026.00 due for the sim card I use for my ****le that has 2GB any time & 3GB midnight on it. I have NEVER used all of my data in the 18 months I have had it. Now they have suspended my service cause I have not paid it & I wont pay it as i didnt use it! You battle to get to someone @ customer care that is not a answer machine & then they know nothing, are rude and all they can say is WE WILL INVESTIGATE IT AND CREDIT YOU IF THERE IS SOMETHING WRONG! They still investigating my account for December that was over R1200.00 instead of R532.00. I paid it & no answer from them. Last month my account was R1600.00 instead of R532.00 where do they think i must get that to pay! Im really really dissapointed in your service & I cant even get to speak to a manager. Will not be surprised if I get no response here either.
