Metro fibre is a bunch of ******!!!

I have had nothing bt terrible service from Metrofibre. My line speed is not what I signed up for. They tried to sort it out bt was unsuccessful. I did cancel my subscription with you. You guys keep on sending me emails asking for payment!!! What a f@#@n cheek!!! Haven't used the internet for weeks and you still expect payment after you sold me a product that you falsely advertised the line speed wich I never recieved. Customer service is poor!!!! No ones gets back to u you!!! Only emails for payment!!!!! Service is worse than telkom!!!!
