LTE advanced @ 512k

<p>I recently got myself a telkom LTE advanced contract and all was fine for a month or 2 with about 60mb speed, then over night the speed dropped to anything from half a meg to 5meg. Its been a month now, all i get from customer care is promises to get it fixed!!! We have 3 LTE advanced instl in our building, all with the same speed reduction. My guess is Telkom is intentionally decreasing the speed for they discovered they cannot maintain the speed advertised. we have a contract! The website say we can get up to 90meg speed...</p>
