MWEB's shame - treating a long-term customer as if they didn't exist.

I've been a loyal Mweb subscriber for more than 12 years now, first ADSL and then, last year, to cut costs, I opted for the LTE service, which more than meets my current needs. After some falling and getting up (Mweb's side), I got my 2-yr contract, outsourced to CellC. Earlier this year I was informed that this service would be discontinued, in my case, as at 31 December 2019. I opted for the Telkom LTE, because I don't want to pay the ******ionate fibre price offered via Vuma. Things started going bad again. They announced a delivery date in October, I told the courier company I won't be here etc. You know the rest of the story - couriers still turn up at my door while I was away. Things went from bad to worse. I had spoken at length to one of their agents (on share call), who then told me she was connecting with the appropriate department. The line went dead. This after 20 minutes on the phone. In the end, I opened a query via my Mweb account on their site on 2 December. Earlier this week, I checked and found the query had been 'closed' without anyone contacting me. I wrote again, twice, and have not heard a word from them. I'm generally a loyal customer, I don't hop round from one 'good deal' to the next. But this really is the pits. If this is the way they treat a 12-yr-long customer, I want nothing further to do with them. Shame on you!
