*********** service!!!!

Changed my banking details in February and they have not been debiting my account since then, I called every month since March to ensure that they debit my account,however, no debits were taken, instead I am harassed with emails informing me that i have defaulted with my payments. On the 9th of June I sent an email requesting that they please call me back with regards to my account after again receiving emails from tracker. They only got back to me on the 23rd of June, 9 working days later! The lady who I spoke to on the 23rd assured me that they would debit me a discounted rate as, the issue was on their side to begin with, however this morning I see that they debited way more than they should have. I contacted the consultant that I dealt with on the 23rd, only for her to revert back to me and inform me that they cannot refund me but they will be adding that amount as credit to my account. This is absolutely unacceptable and ridiculous service. I have chased them for months to ensure that my account is debited! I need this sorted ASAP!
