Extremely Poor Service

Made payment in November to Rain but my services still suspended despite providing proof of payment. Made additional payment in December while awaiting allocation of amount paid in November. Ultimately canceled my services due to frustration. Visited the store returned the router and provided proof of the missing payment for refund. Its 5 months todate and Rain hasn't allocated the payment despite having provided them with exact account number that has tracing number and time the deposit was made. I have been promised that someone will call to resolve the matter. I have escalated the matter more than 10 times with no resolution. Rain is not prepared to resolve customer complaints.
