Poor LTE speed / Poor customer service

<p>I have been having a problem with my LTE connection for a while now, it is very slow and unstable. The people in Telkom stores are severely rude and unhelpful, all they can tell me is to log a call with the call centre. This is a problem as I had a similar situation in December and waited 2 and a half months for a technician to come out after logging the call. I work from home on an hourly basis and need my internet to be working in order to make an income. I cannot wait for the technicians to get back to me as I have no idea how long it will take and need this to be sorted out immediately. Is there anyway to contact somebody higher up in the department??? This is completely unacceptable service!!</p>
