Miladys is harassing me!!!!!

Miladys seems to be harassing me. Every month form the 20th they send met threatening sms's and call me regularly to say that i have to pay my account by the last day of that month. If I'm not mistaken i have until the 7th of each month to pay my account and I don't appreciate being threatened!!! When i visit the store and they check my account details, they say I'm payed up to date, still I'm being harassed every month! When i don't answer my cellphone they call me on my work line. this is absolutely unacceptable! I am a loyal customer and now I'm being treated like a creep who doesn't pay their account each month. If this is how you treat your customers, i will gladly close my account and discourage all they women in my family (who only shop at miladys) to take our business elsewhere.
