No feedback about very slow internet.

Internet speed has been really slow for the past 20 days. I am paying for a 4meg ADSL line. Download speeds of: (346 kbps download) and (upload: 334 kbps).Called customer service and logged the fault 28/02/2016 (ref 1CTK250216) i got an sms on 29/02/2016 that the fault was resolved but it was not. And again logged a call on 01/03/2016 ref no (650CTK010316) got an sms on 03/03/2016 that they said it is handed to there repair division, and the same day got a sms that thy said it was resolved but it was not ? Logged a call again on 05/03/2016 (Ref 94CTK050316) got a sms on 16/03/2016 that the said problem is resolved but again it was not? Telkom send a technician to my house (12/03/2016) and he tested it and said that there is a problem and that they will look into it, until now,nothing is been done? STILL sitting with an internet connection of 0,34mb that is so slow that i hardly cant use. This is absolutely unacceptable and it is a very POOR service for the money im paying for. IF this continues i will have no choice but to cancel my line with telkom. Im really fed up with all there excuses, this is going on for to long now.
