BAD CONNECTIVITY

On 01Aug2020 I received this email from MWEB: 'Octotel, the Fibre infrastructure provider that your Fibre product uses, have informed us that they will be increasing the cost of your current product. Due to these increases from our suppliers, the cost of your product will be increasing,' (The price and speed changes will be effective for existing customers on 1 September 2020 and will automatically be app**** to your next bill.) They added that I should be pleased to know that the new product upload and download speed would increase from 10mbps to 15mbps. This is NOT TRUE. There are continual bad connections and speeds dropping to below 0.8mbps. This is unacceptable. I called the technical division and they said they had sorted it out. Speed improved for a few minutes and then dropped off again. PLEASE RESOLVE THIS! I use Zoom to teach classes and cannot continue with this bad connectivity.
