One month on...No assistance

I am a Telkom LTE customer. My LTE router and internet worked fine until just over a month ago where the speeds slowed down drastically. I currently get less than 2mb/s on an LTE router. <br> I have complained and complained to Telkom, logging my first call on 19 March. I was told someone would assist me in 72 hours. I have since called back 3 times only to be fed the same BS. It's over a month now and Telkom are only too happy to debit my account for a product that does not work. <br> I have tweeted at them, called the call center, and even complained online twice via their online chat option. <br> One month on, no solution, no follow up call. Nothing. <br> <br> This is absolutely shocking service and I would strongly discourage anyone from using their services for anything.
