bad service

i paid up my makro account of the 04 apil already. I kept calling and everytime i was told to call back because it takes time to show. I finally had enough about makro who kept advising they did not receive my payment and got proof of payment and sent it through to them. i called back and they cnfirmed it has been received and they will allocate it to my account. TO date it has not been done yet and they telling me the same story to call back after a few days again but i cant because i was told this since the 04 april and if i call back in a few days there might be anther story. my account is paid up i want it closed, how long does it take to allocate a payment to the correct account especially if you know the client has been calling since the 04 april but i guess they dont care, because they dont even bother to g and check their notes and nobody is willing to assist. Im hapy that very soon the account will be closed.
