Frustration for Mondo / Rewardsco

My name is Kaashif Gafieldien with ID number *** and cell contact number ***. I have cancelled a Lenovo laptop from Mondo MTN in April 2023. A weeks later I could again but a different 1 according to my credit limit. Their *********** staff debit my account with the full price of the 1st laptop contract and has promised to reverse and credit my account. I am still paying my normal monthly MTN subscription whilst service has been suspended. When emails are sent to Mondo , no reply is sent. When calls are made to this to permanently resolve their problem , I get put on hold for sometimes 40 minutes. I'm also still waiting for a re-imbur*****t of devices I have paid in while waiting for it to be cancelled. Emails and calls do not work for trying to resolve this problem
