I cant help you,everyone is on holiday

I have been receiving sms over the past few months saying my account is overdrawn. I have brought this to attention of my branch as it is not overdrawn and they say it is a wrong number on the account and will sort it out..Today I received an sms with a call number and a reference number. I called giving the reference. I was told by Mr Matseke that it wasnt my name on the account. When I asked him to remove my number from the overdrawn account, I was told he would try. I asked him to tell me that I would not receive anymore sms like this one and he said he couldnt. I asked to speak to the supervisor,and was put through to Mr Maditsi. He said he would need to investigate but everyone was on Holiday so I need to give him a week. I pointed out to him that this matter was long overdue in resolving and gave him 45 minutes to come back to me with an answer. After an hour and a half,I called him and was told he was busy. I said I would hold on. I was cut off twice. Eventually after speaking to Mr Maditsi,I was told that this sms was not generated by his department. He would investigate furthe. He also told me his supervisor and his supervisors supervisor are all on holiday.
