Telkom offering worst aftermarket service

We wanted to apply for telkom LTE internet, so we phoned telkom regarding this matter. We got in contact with Joy who is a sales person. we sent through all the documentation, and after that we could never get hold of her again to find out how far they were with the process. So then we changed sales people since we couldn't get hold of Joy, and then worked with Mufundo. We submitted all the documentation again, and he assisted us up until we got our Huawei modem. Now we want to activate our sim card so we can finally have internet again and guess what, no one can assist in this matter once again. So telkom tell me, do you want my business or should I take it some where else. If I cannot get support or help from you, then I do not see why we should even pay for the internet. If this matter does not get resolved, I will simply not make payment then we see how fast you phone me.
