Utterly poor service from MWEB

I ordered an MWEB LTE deal for 125GB + 125GB nighttime data via MTN monthly at R629. I was told that my current Huawei router would not suffice and I bought the recommended ZTE router for R1499. The delivery took place at about 08:00 on Monday, 12 October and I immediately plugged in the router and SIM as instructed and waited the recommended 48 hours for activation. After the 48 hours elapsed, I still had no connection. I started phoning MWEB immediately and was being transferred from here to there and no one could fix anything. I even got transferred to sales where the agent was confused himself of why I ended up there! I spent one whole day just phoning MWEB. They told ne they would escalate to MTN and phone me back. The NEXT day I received a call from another MWEB agent instructing met to put the SIM into my phone and back into the router and he would phone me after 10 minutes. I WAITED MORE THAN AN HOUR for his call back! He did not even apologise. Still it was not fixed. I have just phoned the technical division again with no solution and requested to cancel my account. I was transferred to the Billing department and placed on hold for approximately 15 minutes. I have tried the online cancellation and it just says "You cannot cancel XX Product. Contact the Call centre". I tried calling again and was holding until my airtime ran out. I have spent a minimum of R200 airtime just trying to get somewhere and I am still not ****her. Utterly poor service!
