ADSL Issue 1month

To whom this concerns. <br> <br> For the past month now, I have been struggling with my adsl at home. During the day from about 07h00 in the morning till about 21h00 in the evening. It keeps disconnecting every 15 to 20 min, losing sync to the exchange. I have tweeted probably a 100 times, phoned the helpline a few more and got no solution to this problem as yet. I thought perhaps it's the modem, so I go to the Telkom direct store in Clearwater yesterday after I have been trying to contact the store for the entire day to no avail. I arrived at 18h10 with the expectation that the store will be closing as per the malls trading hours. All I wanted to know of, is if they can log a call for me, or how I can have my router checked. There were still a few customers in store including staff. I knocked and the security guard chased me away with her hand like a dog. The rest of the staff blatantly ignored me, till eventually a customer left and I stuck my head through to just ask my question. To which I got the response \log a call and get a reference number". Worst service I have experienced in a very long time. It's definitely not my router as it functions 100% after 21h00 in the evenings. Help? """
