No Connection

I live in an area with very poor signal after years of struggling it was suggested that we put in a Telkom LTE, We got in a professional company to install special aerials so that we could at least get a 2-bar signal. All was installed and working well. We purchased a 60GB package from Telkom which lasted about 8 months, purchased another package and got a similar time. I went to purchase a 3rd package and was told that they are now only 50GB (for the same price) but now I get roaming. That's when the problems started because apparently the unit now looks for the MTN signal - which is ******* in my area. I went back to Telkom and asked them to take me of roaming - they said it can't be done but would register a complaint and I would be called - 4 days later still no response. I got a direct email address for Keith @ Telkom Data - No response to emails sent to him. I called the call sentre and spoke to Sonto Majola, after about 20 minutes of being on hold, speaking to her, being on hold I was told that they can not look at it as their network is down and that I should call back later or tomorrow. After a short discussion she agreed to call me back with a solution.
