Wireless LTE Speed Problems.

Signed up with telkom for their Wireless LTE package which promised a speed of up to 90mbps. First 5 months had no problem and I was happy with the 25mbps I was getting but recently my speed has gone down to 1 - 2mbps.<br> I have called Telkom, spoken to them on the chat line and have tried to call 2 different stores (Westgate and Clearwater) and I can not get the problem resolved.<br> Now I know why maybe people stay away from Telkom, the after sales sales service is non existing, staff are *********** and product knowledge is close to zero.<br> I am paying for so called high speed Internet and I am not getting it, that is a breach of contract.<br> Telkom come to the party, please or I may have to resort to legal action.
