*****ing money ***** !!

Yesterday I was upset by Telkom having spent over an hour on the phone around an LTE Deal I app**** for, I am none the wiser what is happening there, and gave up with the operator. Today I received an invoice for an existing data package I have had for almost 3 years ( originally a R199 a month Package), switched to R299 at the end of the 24 month contract . has been running like this for a few months now. The latest invoice shows a Data usage of R500 on top of the R299. I rely on the out of bundle message to swop sim cards in my modem ( Yes I have two sim Cards). So without any notification or warning they have allowed the sim to continue working raking up a huge account R500. I contacted them immediately and asked that the situation be rectified, which has been done, but effective only on 1st of June, so this month they are going to rob me again. I Had great difficult communicating with the agent, almost as if we where not speaking the same language. This is really not how you should be treating loyal customers wish I new how I could resolve the matter
