Shocking service and network connectivity

My Telkom experience the last couple of weeks where shocking. I had perfect LTE (4G) connectivity at my house and I could watch netflix, DSTV and any other internet related program , download was great and I got throughput of 25 Mbps and upwards and it was stable. Every now and then they hit a glitch. I jump onto Twitter @telkomsa reported the issues and they resolve it quite quickly great experience I upgraded my package from 100GB a month to 200GB. Since last week my internet is shocking. I gave them the info as normal but there is no answer. I tried logging call on their website and that only give me the run around. Tried phoning their contact centre and they keep me on hold for 45min. This is absolutely shocking service and I am about to cancel all my contract with Telkom. Was great until now. We are paying Hugh amount for data but if this is the service I get I might as well leave it. I am at your outlet on Saturday, I f this is not rectified I will cancel my contract and never take Telkom contract again and I certainly know that I am not the only one with this problem. Telkom stop selling and start looking after your network and your customers you are letting us down
