Poor Communication Lines at Mweb.

I have lost over R300 on telephone calls, trying to contact Mweb and each time I am told to wait and I hold for more than 30 minutes each time, till I give up. I want to make changes to my order for LTE service now instead of waiting for their courier to deliver and I turn them back. Instead of LTE I want them to change me to Naked ADSL which was recently introduced by Openserve as at 29 March 2020. I prefer this because of its "Uncapped Option" and less costs. My account number at Mweb is ***. I have already paid Mweb R2000 in advance for LTE router but do not want it anymore, rather I must be shifted to Naked ADSL which does not require a copper landline as prerequisite. Mweb is the best company I have been with but lately are proving very difficultto contact.
