Worst Experience Ever

I requested to cancel my services so I can move to Clear Access as it has been an uphill battle from the start and nevermind the fact that you can never get anybody to assist on that WhatsApp or call anybody when all that fails but was advised that there was no need as they will be able to match the price I got from Clear Access, plus give me a month's credit.. what happened next was just a battle from hell, I was upgraded on the billing but still was getting my previous speeds which were 8mb, then billed for 25mb line which they expect me to pay but I am not on the services then the credit was never passed or the price match so I was charged for that as well and now nobody from the Technical, Customer Service or Retentions know what to do and I have been transferred for more than a couple of days to different departments only for them to go offline after and we do it again the next days since the 24th November...
