Contract

In september I upgraded my home internet to the special for the month of September 500MB +10GB per month for 24 monts. On 6 October the internet was depleted. When visiting the the shop the staff indicated that they accidentally did not load the 10GB. (It worked well in September). Then I received a reference number and they told me the problem will be solved in 5 days. First of all, why should it take 5 days to fix the problem if they can sell me any product and activate it in a few minutes after signing the contract? A problem like this should be fixed right there and then! It is today 21 October, no feedback yet. I have to buy prepaid internet to do my daily activities. In the mean time I have a debit order on my contract but I dont receive the product I am paying for.

This is a huge concern for me.
