City of Cape Town accounts department.

Hi, i have a couple of properties on my name. i always pay my rates and taxes on time,but March 2018 i have not received any invoices. when i phone them they said my email address was wrong, which is very weird as i have been receiving my accounts on the same address for many many years. So someone on their side must have change my email address. The only way to fix this is to sms your account nr and your email address, but i am still not getting any accounts. eServices also do not work and just shows IN PROGRESS for the last year. WHAT DO I NEED TO DO!!! the one account is over R11k. all i want to do is pay the money. if you phone them you are listing to classical music for ages.
