Morclick claiming money for services not received

I signed up for internet services with Morclick in 2021. At the time my daughter was doing online schooling and i advised Morclick that i was in desperate need of a good reliable internet connection as my daughters online studies were my number one priority. Morclick promised the world. They proceeded to put up all their equipment and got us connected to the internet. From day 1 we had issues. I spent my life emailing and telephonically engaging with Morlcick about the non service that we were receiving. The internet connection for the majority of the time was non existent, and if it did work you couldn't even watch a you tube video on your cellphone. My daughter ended up missing numerous classes due to having no internet and the more i complained, the more nothing ever got done. I ended up having to buy a mobile router and load data which ended up costing me a fortune to just enable my daughter to attend school. I was paying more for data for the mobile router than i was for Morclick. I begged and pleaded with Morclick to resolve the issue however whatever measures they tried it never got resolved. I eventually got to a stage after hundreds of emails and phone calls that i simply could not pay for a service that was non existent. I did Email Morclick and tell them that i was going to stop paying because i cannot pay for something for nothing and i was having to buy data for my mobile router which was costing me about R1500 per month. I have subsequently been threatened by Morclick for non payment and they have put a negative mark against my name with the credit bureaus which has had a hugely negative affect on my credit rating which i believe is totally unacceptable. I understand there are clauses etc in the agreement however how can you pay for something that you simply don't get ??? and i had to make an alternative plan which was costing me approximately R1500 per month. Lets hope Morclcik does the right thing and drops this as any reasonably minded individual will understand where I'm coming from however Morclick will not give up hounding me for R6900 for services that i simply never received. I have all the correspondence throughout the entire process where i was begging and pleading with Morclick however they still want money for services never received. Account number : A2931
