Bad 3G connection.

We got our self a 3G/LTE modem(Huawei E5372) and data contracts form Telkom Mobile on the 23/02/2015 2 Weeks went by and our connection speed was still very slow about 1-2Mbit/s on 2-3 Bars of 3G signal strength(no LTE what so ever) with the added problem of losing connection fairly often, we log a complaint at the Telkom store were we brought the device. About 2 weeks later the technician shows up and detriment that there must be a problem with the tower the modem needs to connect. The technician assured me that he will escalate the problem and I should be notified within 15 days that the problem will be fix. 3 weeks went by and still no word. Then I received a phone call from another technician also wanting to come and inspect the problem. The technician shows up the 15th of April with equipment to test the signal strength, with these test it was detriment that my modem will not be able to receive LTE as I am 27m above the nearest tower and a signal booster will be needed for the 3G. The technician also informed me that I should within 8 working days receive a call to schedule the installation of the boosters, that was Monday and still they expect to just pay each month.
