No response in 5 months

In September of 2013 i took out a 24 month 5gig a month contract with Telkom Mobile, everything went well and fine until upgrade time came- I believe June of this year- i was advised I wouldn't be put on a new 5gig a month but it would now be 1gig, which i was fine with, but I already had a 24month agreement with them where they would have to give me 5gig<br> <br> They only gave me 5gig till the 20th month and changed me to the 1gig upon upgrading but charged me for the device until the 24th month, and even that one gig they didn't give me on the first month instead only giving me 150 meg. I opened a case with them on the 1st July asking for my remaining 4x5 gigs(4 remaining months) as well as a refund of the money i had to spend buying data in July due to them not loading my contractually agreed data<br> <br> I have not had any feedback from Telkom from the 1/07/2015 until today the 04/11/2015 and every time i call them they say they cannot transfer me to 'back office' but they will send an email- they have sent tons of emails and nothing has been done up to this day-<br> <br> Useless company, in a week I'll be writing to Icasa
