Pathetic service at Vumatel and MWEB

Kindly note that I have had a horrible experience with MWEB and Vumatel.I had requested a downgrade on my line.The problem started when they did not deduct their money from my account on the 30th of June.I thereafter enquired and requested the payment link.After eventually obtaining the link I managed to make a payment on the 9th of July.There has been no internet connection since then.I have sent numerous queries and spoken to agents and was promised that my issue would be resolved.I have been receiving emails for scheduled appointments for technicians to attend to the matter as of the 16th of July however till today there has been no resolution or any technicians attending to the matter.I have run out of options.I need assistance as soon as possible and to get the internet up and running.Your prompt response would be highly appreciated.
