Holding on to money that does not belong to them!

Every aspect with them has gone wrong, so I would not even know which problem to start with. I was sent a router that I ordered to find out that the area I live is not covered. Apparently I gave the incorrect address where I live while I was standing in my house. This is also quite strange as the probably 15 times I had to follow up with them I had to give all my details to be identified, before we could continue with the conversation which included MY ADDRESS.

Eventually two weeks later they collected the router! (numberous calls later) I was told that my debit order could only be reversed once they collected the router. After the router was collected I once again spoke to MWEB to ask them for a date when my money will be reversed back into my account. I was told that it would take 7 days. Today - 8 days later, I phoned again to follow up once again and now I am told that it takes 7 days to pass the credit and then another 10 days thereafter for the money to be reversed back into my account.

How on earth is it possible that I have to wait for almost a month to get MY hard earned money back for a service that I paid for ON TIME and was not provided?
