Bad Customer

I recently took a fiber line through Vuma Tel and Afrihost being the service provider , I had an option of using other service providers but I decided to use Afrihost as I had previously dealt with them , In essence my reasons for using them was out of loyalty . Little did I know my loyalty will be thrown back at me by Afrhost . I made payment and my fiber was installed , I even put my banking details for my installment's to be taken every month , Second Month my services was disconnected due to none payment as my expectation was for them to debit my account, none the less that didn't happen so I made a manual payment then i contacted Afrihost to reconnect and give me a way forward in terms of debiting my account , Only to be told that I should have paid Vuma and not them , Mind you my first payment was done to Afrihost so naturally I paid them again . Afrihost afford to refund me so that I can go pay Vuma Reach, They also claim to have refunded me but nothing is in my account yet . So I went to Vuma Reach and will called them for clarification , now to my surprise and all of a sudden i owe them money from my previous dealings with them , They say I owe them since Jan 2020 , Surprisingly they have given me a new line and and had accepted my first payment and they also refunding me so how does that work ?? Secondly why did it take them this long to inform me that I owe them ?? I have never received any communication and I am only finding out now that I have outstanding amounts ?? I have since cancelled my subscription with them but now they blocking me from getting a line from a different service provider cause they only willing to release the line at the end of May . That's how powerful they are
