Change of Bank Details

In September I changed from a Nedbank savings account to a Nedbank cheque account as the bank charges were too much. Nedank emailed all my service providers including WW. I have for the past few weeks been trying to ascertain whether my new bank acc number has been updated. I have emailed a few times, phoned and personally went into the Blue Route branch and they sent a fax off in front of me and handed me proof that the fax had been sent. <br> On following up again at Blue Route I hear that nobody followed up with a phone call after the fax was sent which is their standard procedure. I don't understand why this is now my problem? I took the transmission log and left thinking that this would now have been sorted. Yesterday i am told that i must personally go in and make a cash payment as it's too late for the debit order run! How long does WW need if the instruction was given in September and now in November no bank details have been updated yet! I find this ridiculous and on messaging WW on Facebook, I get asked every time to provide my ID number and someone will get back to me. I have lost count now, prob 5 times or more I have issued my ID number. Please WW sort this out!
