Changed for nothing and super bad service from Mweb

Firstly Mweb said that it could take 14 business days to install our fibre, it took more than 18 days. Secondly we had to change the OTP cell number to be able to activate our service, we submitted the forms on 13 December, on 31 Dec we phoned them to follow up since there was no progress. The lady said someone will phone back in 15 minutes, 4 hours later we phoned again and once again Mweb said someone will follow up shortly. Now it's 3 Jan we had to phone them twice already today and apparently someone will phone back in 30 minutes but I will not count on it. Above all they confirmed that the docs we submitted on 13 Dec was correct. But their invoice was on time for a service we don't have yet because they won't change the OTP cell number. Hopefully they don't expect us to pay for a service they refuse to deliver. Reference number: mwb***0.
