only get 50% upload speed, technician found no problems

Hello, I have CL DSL as my only internet option and the max speed I can get is 1.5mbps down with .2 mbps up. I've had it now for 6 years and they've not updated anything to get better speeds. This is already too slow for modern content and especially streaming services. The upload rate barely makes basic document uploading feasible and anything beyond that takes all day. For about 3 weeks now I've been getting half my normal upload rate. It's usually less than 100kbps. I've not been able to really do much of anything with that speed. I do a lot of gaming, VOIP and work from home stuff which was OK with my normal rate but impossible now. I've put in 3 requests for a repair. Finally today a technician came and saw no issues with my line both on the box on the side of my house and inside on my modem connection. I'd already tried 2 modems and multiple devices and wires to check speeds with the same results. He gave me a new modem (ZyXEL PK5001Z) which is also showing the same 50% or less upload speed. It has a bit more info than my other modems, though, so here's what it shows for my connection: DSL Status Connection Status DSL Downstream: 1.528 Mbps DSL Upstream: 0.133 Mbps DSL Link Statistics Link Statistic Status Broadband Mode Setting: MULTIMODE Broadband Mode Detected: ADSL_2plus DSL Link Uptime: 5M:31S Retrains: 6 Retrains in Last 24 Hours: 6 Loss of Power Link Failures: 0 Loss of Signal Link Failure: 0 Link Train Errors: 3 Unavailable Seconds: 495 Transport Mode: ADSL Path Parameter: 8/35 Priority: UBR without PCR Service Type: LLC Bridged DSL Power Levels Downstream Upstream SNR 23.9 dB 36.2 dB Attenuation 16.5 dB 9.8 dB Power 18.3 dBm 0.4 dBm DSL Channel Levels Near End Far End Channel Type: Fast Interleaved CRC Errors: 260 0 15 Minute CRC: 0 0 RS FEC: 87500 0 15 Minute FEC: 0 0 Here's my most recent speed test: http://www.speedtest.net/result/4921865343.png Is there something on my end that I am missing to check, or something to go over with the technician? He is supposed to be coming by again tomorrow. Thank you.
