Promises and more promises - ridiculous service!!

I have been complaining to Vodacom for most part of my 2 year contract about not being able to use the data on my contract package. Their marketing angle on the package that I am on, was that I can have all these voice calls and then use the data in my office, as I get the data sim card with.<br> <br> I requested numerous times that a booster be installed in the office, as there is no signal. After more than one hellopeter complaint, a technician came out in April 2015 - after almost a year of complaining! He confirmed that a booster is needed in the office and that he will come and install one as soon as he can. That was in APRIL already!!!!<br> <br> Vodacom promised better reception after October when they were planning to upgrade their site closest to us. Now the signal is even worse and we cannot even get a stable EDGE connection.<br> <br> I have been a Vodacom customer for 20 years and it is sad that I am considering moving to another network.<br> <br> After my previous complaintS, they phoned to say that they looked into the issue and yes, the site has not been upgraded yet - but they offer NO solution OR follow up? Just promises about a technician that will AGAIN (WHEN??) come to investigate... <br> <br> None came
